The two basic requirements that allow a lawnmower’s engine to startup are fuel and a spark. If you are experiencing fuel starvations (when fuel is not getting to your engine), or if you are not getting a spark at the plug, your engine will not be able to startup.

Bad compression can also be a reason for experiencing difficulty while trying to start the lawnmower’s engine. If you pack the lawnmower away for the winter with fuel still in the tank, the seals, valves, and pumps in the lawnmower’s carburetor can become blocked up with varnish deposits. Along with this, dirt and dust can get collected and end up blocking the fuel system or clog filters.

Before You Start Troubleshooting On Your Mower You Should:

Proceed with caution when working with your mower. You should first start by removing any sources of ignition. This includes cigarettes, naked flames, sparks, stoves, or other hot objects that are in the same area that you intend on working on the tank or fuel lines.

Be sure to do this if you need to remove any clumps of grass that may be jammed under the deck.

This is to avoid the oils in the mower from spilling, as this is likely to happen if left on its side.

This can be avoided if there is a small amount of gas in the tank, or if you do not think that it will reach the tank cap. However, if you are unsure of this then it would be best to just drain the tank. Another trick is to open the cap and then place a plastic bag over the opening and then put the cap back on.

You are likely to cause premature engine wear if the oil level is low. Added to this, an engine can seize quickly if there is no oil present in the lawnmower.

Checking On The Oil Level Of Your Lawnmower:

Before starting the process of troubleshooting, you should make sure that the oil level in the lawnmower is deemed acceptable. You can do this by:

• Move the lawnmower to a surface that is level.
• Remove the dipstick and wipe it clean.
• Place it back in the lawnmower and then remove it again.
• Check to see where the marking is. If it is relatively low, top it up to the necessary level.

You should make a mental note that the oil in the tank should be changed after every 25 to 50 hours of run time or as advised in your engine manual.

Tips To How To Get Your Lawnmower Started:

How Do You Start A Lawnmower With Old Gas?

Although, it is recommended to drain the lawnmower’s gas tank before it sits for a long period of time without any use. However, most people do not do this. The result of not draining the gas tank causes residue build-up. If this occurs, you should refer to your lawnmower’s manual for information on how to remove this build-up from the fuel tank effectively, as well as for service procedures. Or see our guide on this problem.

As soon as the build-up has been cleaned out, gather all the old gasoline and put it in a container to dispose of it properly. This can be done by running a siphon hose from the gas tank to the container and then pumping the bulb a few times. In doing this, you are moving the gas from the fuel tank and draining it into the container, which thereby cleans out the lawnmower’s fuel tank.

If your lawnmower still is not working after you have cleaned out the fuel tank and adding new gasoline to the mower, you should make sure that your spark plug is working. There is a large possibility that the spark plug wire will become loose after being stored for long periods at a time.

A common problem found when trying to restart a lawnmower that has been stored in that the carburetor gets flooded. Be sure to note the smells and sounds of the lawnmower while you are trying to start it. A strong gasoline smell could mean that the carburetor has been flooded, and as a result, the lawnmower will not start. In this case, you should wait a few minutes before you try to start the mower again.

How Do You Dispose Of Your Lawnmower’s Oil?

When cleaning out the oil in your mower, be sure to collect in a bottle-like container that screws shut. This is to prevent any spilling. Your local mechanic or oil change shop should usually take your used motor oil to dispose of properly. However, if this is not possible, there may be disposal programs for motor oil at your local dump.

If smoke is coming out of your mower, this could be a sign that the oil needs to be checked and changed. However, a lawnmower that will not start obviously will not smoke. Nonetheless, this is a good sign to look out for as it will allow you to stay on top of your lawnmower maintenance. Added to this, smoke coming from a mower could show that there is a leak somewhere. The leak causes the oil to burn when it lands on hot surfaces such as hot metal. Along with this, smoke can also indicate that there is not enough oil in the lawnmower. Not enough oil has the potential to cause permanent damage to the engine of the mower.

What Are The Options For No-Hassle Gas?

One form of no-hassle gas is a product called TruFuel and it is available in most hardware stores. Known to be “old school” gasoline that has no added ethanol. What is so great about this product is that you do not have to add any fuel stabilizers. It runs clean and can sit in storage all winter and will still start up very easily.

However, it is more expensive than regular gas. Nonetheless, when you weigh in that while using no-hassle gas you will not need to pay to replace your lawnmower or carburetor every few years.

How To Fix A Flooded Carburetor Lawn Mower

How To Fix A Flooded Carburetor Lawn Mower – A problem that often occurs lawn mower are flooding carburetors. A flood carburetor is damage caused by a damaged carburetor component. In this article will be discussed about the causes and how to fix the carburetor of a flooded lawn mower.

The carburetor itself is a component of the gasoline engine that serves as a fuel supplier to the combustion chamber. In lawn mower, carburetors often experience flooding that results in the machine becoming unable to be turned on. For that, it is important for us to know how to fix carburetors on flooded lawn mower.

In addition to the engine is difficult to turn on, the result of other flood carburetors is wasted fuel. Because it will continue to flow out even if the machine is in a state of stop. Therefore, if you experience problems with carburetors, it must be repaired immediately so that the lawnm ower can be used normally. Here is a discussion about the causes and how to fix the carburetor of a flooded lawn mower.

How To Fix A Flooded Carburetor Lawn Mower

There are several problems that cause lawn mower carburetors to flooded. Among them are as follows:

Dirty Fuel

One of the causes of flooded lawn mower carburetors is dirty fuel due to mixed dirt. Problems like this are usually caused when refueling without filtering. So that dirt from outside will mix with fuel.

When the fuel mixed with dirt into the carburetor, it will cause the air gap in the carburetor will be clogged. Thus resulting in the absence of air circulation in the carburetor and fuel will look for gaps to get out of the carburetor.

How to fix the carburator of a lawn mower caused by this period is to drain the fuel in the fuel tank, then clean it until clean and dry. Then we also have to clean the inside of the carburetor. Because it is likely that fuel mixed with dirt has entered the carburetor. Once the carburetor and fuel tank are cleaned, re-fill the fuel into the fuel tank.

Carburetor Float Needle Is Damaged

A carburetor float needle is an automatic open lid valve that regulates the entry of fuel into the carburetor. If the carburetor space has been fully filled with fuel at a predetermined limit, then the carburetor float needle will immediately close the flow of fuel flowing into the carburetor.

If the carburetor float needle is damaged, then the valve will not close properly and result in the flow of fuel will continue to flow into the carburetor even though the room has been full at the specified limit. So that the fuel overflows and flows out.

Problems like this can be solved by replacing the new carburetor float needle. However, it should be noted when replacing a carburetor float needle should have the same shape and size. Because each lawn mower has a different size of carburetor float needles.

Carburetor Float Too High

The third cause of a flooding lawn mower carburetor is the arrangement of a carburetor float that is too high. The carburetor float is the part that serves to regulate the low surface of the fuel accommodated in the carburetor space.

If the setting is too high, then the carburetor float needle will not be able to close even though the fuel has been fully charged inside the carburetor room. So that gasoline will overflow out of the carburetor.

To repair flooded carburetors caused by carburetor float too high, namely by changing the height of the carburetor float according to the average standard. And try not to be too low, because it can cause the fuel too efficient and the engine becomes hot quickly.

Thus the discussion about the causes of how to fix a flooded carburetor lawn mower. Good luck.

Why Is My Lawn Mower Spark Plug Wet? (And How Can I Fix It?)

So you are here because you are asking why is my lawn mower spark plug wet?

It is a valid concern, as these small pieces of equipment are what essentially make your mower’s engine produce power by supplying the spark to ignite the mix of air and fuel.

If the spark plug is wet then it makes doing this A LOT harder!

Let’s take a look at what can cause a wet spark plug and how to fix.

Why Is My Lawn Mower Spark Plug Wet?

If your lawn mower spark plug is wet, then it will nearly always be wet with oil or without petrol. If it is wet with petrol it is often because either you have flooded the engine when trying to start it, or too much fuel is being allowed in the carburetor. If it is wet with oil usually either the tank has been overfilled, oil has leaked onto the plugs when it has been tilted or the piston seals are worn.

What Are the Symptoms of Wet Spark Plugs?

Let’s ignore the most obvious symptom of a wet spark plug for now (it feels wet…).

Beyond physically looking at, and touching the spark plug, there are a few telltale signs that there is an issue with your lawn mower’s spark plug:

• Your Mower Is Difficult to StartThis is the most common symptom of a faulty spark plug. It isn’t properly producing the spark to ignite the air/fuel mixture and start the engine. It might take several pulls on the starter rope or turns of the engine to get your mower going.
• Your Mower Isn’t Running ProperlyWe can all immediately tell when any piece of mechanical machinery isn’t performing to its optimum levels. It might keep dying out, spluttering or faltering. This could be because a faulty spark plug is causing the engine to misfire.
• Your Mower is Consuming a Lot of FuelWhen a spark plug is faulty the fuel is not being burnt properly, thus the mower is less efficient and fuel consumption is higher. Often the fuel will emit an unusual odor as well.

If you notice your spark plug is wet, then it stands to reason that it will have been made wet by one of two substances…

Why Is My Spark Plug Wet With Petrol?

If you are finding the spark plug on your lawn mower is wet with petrol, there are two possible explanations.

Reason #1: You Have Flooded the Engine by Excessive Use of the Choke

Overly using the choke when starting your mower will flood the engine with too much fuel and not enough air.

The plug will become fuel fouled as a result and not spark.

How to Fix This

If this is the problem you can either:

• Remove the spark plug. Pull the starter cord a few times to get rid of any fuel from the cylinder. Reinstall the spark plug when it has dried out.
• Remove the air filter and put some starter fluid into the mouth of the carburetor. The starter fluid should get the engine going, and then combustion process should dry the spark plug.

Reason #2: There Could Be a Problem With the Carburetor

If the above doesn’t appear to be the issue, then there could be a problem with the carburetor.

Often the cause here is linked to the carburetor float needle and seat. They might be worn out, the fuel float could be leaky, or something (such as dirt) could be holding the needle off its seat.

What then happens is too much fuel enters the float chamber and is passed into the carburetor.

Air pressure forces excessive fuel into the engine flooding the spark plug.

How to Fix This

If it is severely clogged, then sufficient amounts of air cannot enter the carburetor, which is then flooded by too much fuel.

Also refer back to the owner’s manual. Often failing to follow the correct procedure when starting the mower can be to blame.

#2: Why Is My Spark Plug Wet With Oil?

The other substance your spark plug is likely to be wet with is oil.

Usually, this will be due to one of three reasons.

Reason #1: The Tank Has Been Overfilled With Oil

If too much oil is poured into the tank, the crankcase can overflow, and the oil will leak onto the spark plug.

How to Fix This

Simply remove the oil cap and drain out some of the oil. The best way to do this is to use something like a turkey baster and extract the excess oil this way.

Reason #2: The Mower Has Been Tipped on its Side

Have you recently tilted your mower sideways to clean under the deck or sharpen the blades maybe?

If so, when you did this oil may have pooled up under the piston and either seeped past the piston rings or entered the carburetor via the air intake when the mower was turned on. From there this can cause the spark plug electrodes to become oily.

How to Fix This

You can remove the spark plug and allow it to dry, or clean it with carburetor or brake cleaner.

When you reinstall the plug the engine should dry out any remaining oil on the spark plug.

Reason #3: The Piston Ring Seals Are Worn

The seals on piston rings prevent oil from leaking into the combustion chamber.

If they become too worn, oil can spray onto the spark plug.

How to Fix This

Piston ring wear occurs when there has been excessive use of the engine. It isn’t an easy part to replace and will require an engine rebuild.

If you are mechanically minded you can try and replace the piston rings, but often it is easier and sometimes cheaper to buy a new mower.

Or if the mower is still running fine you can continue to use it.

Wet Spark Plugs and Two-Cycle Engines

Although most mowers these days are four-cycle, there are still some two-cycle mowers knocking about.

If you have a two-cycle engine, then a wet spark plug isn’t actually too much to worry about, in fact it is somewhat normal.

With two-stroke engines, there is always a bit of oil residue in the cylinder, and often this will make its way onto the spark plug.

The mix of fuel and oil that two-stroke engines burn is meant to leave a bit of oil behind as a lubricant.

Lots of excess oil in the cylinder of a two-stroke mower might indicate that you have added too much oil to your fuel.

How to Fix Wet Spark Plugs: An Overview

If you are having trouble starting or keeping your lawn mower running then there could be an issue with the spark plugs.

If they are wet then they won’t ignite properly.

Whilst sometimes water in the tank or injector leaks can be the cause of a wet lawn mower spark plug, this is very rare.

It will nearly always be wet with oil or with petrol.

Most of the time the problem can be fixed without a huge amount of expense. The exception to this rule is if the cause is worn piston rings.

But even then most lawn mower engines are built to last at least five years, so if your piston rings are worn you should hopefully have got plenty of use out of them by this point.

Why The Spark Plug of The Lawn Mower is Wet? How To Fix It?

Have you ever experienced a wet spark plug of your lawnmower? Sometimes, it occurs when the spark plug comes in contact with gas or oil. In this post, we are going to reveal the reason behind a wet spark plug of your lawnmower.

Why is lawn mower spark plug wet?

Wet spark plugs in lawnmowers can occur for several reasons. According to experts, the most common reason is that the spark becomes excessively hot due to the inclusion of ethanol in the gas.

And, there is a flood of oil in the combustion chamber or, the engine is flooded with water/fuel.

Why Is Lawn Mower Spark Plug Wet?

Spark plugs can become wet on a lawn mower for a variety of reasons. When the spark plug gets wet, you need to either clean it correctly or replace it with a new one.

But before cleaning or replacing it, first, you should know why your lawn mower spark plug is wet. Like other moving parts of lawn mower, spark plugs wear out eventually, leading to malfunction.

Engine Flooding

When you often had to try several times to start your lawn mower, it is an early indication of wet spark plugs. Trying this multiple times may lead to engine flooding, which ultimately drenches the spark plug. As a result, the engine is failing to generate any sparks and can’t start the engine.

So, why engine flooding occurs in lawn mower spark plug?

Your spark plug may encounter this issue during freezing weather conditions. In order to ignite the lawn mower engine with previously worn or fouled spark plugs, a higher voltage is required.

Under these circumstances, you should either let the plug becomes dry or take it off from the mower and clean it.

Injector Leaks

Though wet fouling is rare among the latest lawn mower engines, some mechanical problems can occur. Leaking cold start injector is one of the most common issues your engine may encounter.

When this happens, the engine compartment will likely be filled with a rich starting mixture, ultimately leading the spark plug to foul.

Worn Piston Rings

A study done by Mopar Magazine reported that fouling might occur when piston rings or cylinders are worn out in older lawn mower engines.

As a result, you may notice your lower mower engine is flooded with gasoline or too much oil. In addition, an ignition attempt may not be successful if a spark does not form.

In this condition, you can easily handle the spark plug by removing and cleaning it properly and then re-install it in the place where it should be.

Why My Lawn Mower Spark Plug Wet With Gas?

The main job of an electrical device like a spark plug is to source power to start your lawn mower. You always want to keep this electric device away from getting wet to perform consistently for generating sparks. However, it may often get soaked with gas or gasoline, leading to a flooded engine.

Why is my lawn mower spark plug wet with gas?

If a lawn mower spark plug becomes wet with gas, it can happen for multiple reasons such as lousy ignition cable, or engine flooding, or internal crack in the ceramic insulator, or dirt or moisture on the outside of the plug.

When spark plugs get wet with gas, it means the electrodes have not been ignited. If it happens due to a bad ignition cable, the components are unable to carry an appropriate amount of current under heavy load conditions. So, these are the reasons behind a lawn mower spark plug wet with gas.

Why My Lawn Mower Spark Plug Wet With Oil?

By looking at the spark plugs tips and other sports, you can have an idea about its health conditions and how well the engine can perform. You can also get an idea about other problems based on the appearance and color of the deposits.

Why is my lawn mower spark plug wet with oil?

If the spark plug is becoming excessively hot and the chamber is filled with oil, you may struggle to run the mower. There can be different reasons behind lawn mower spark plug wet with oil, such as using a spark plug for too long, excessive choke usage, or stucking issue with the float.

Using A Spark A Plug For Too Long

According to experts, a spark plug needs to be replaced or changed on average after two years. If you use your lawn mower heavily, you may need to replace it earlier.

Excessive Usage Of The Choke

There’s a possibility you have to exceed the choke usage, resulting in excessive fuel in the system. Also, make sure you don’t over-prime your mower as a primer is designed to improve combustion and freshen up gas.

Stucking Issue With The Float

An automatic liquid supply system runs efficiently with a float chamber, which controls the fuel delivered to the system. When the float fails to control the amount of fuel delivered, it may make the spark plug wet with oil.

What Causes A Spark Plug To Become Wet With Fuel On A Lawn Mower Engine?

It is called “fuel fouling” when the lawn mower’s spark plug becomes wet with fuel. A spark plug wet with fuel may prevent you from running the machine smoothly, and you may fail to cut the grass efficiently.

What causes a spark plug to become wet with fuel on a lawn mower engine?

One reason can be to adjust the throttle too aggressively or too tightly, which prevents the plug from having sufficient air. Or, you may have spilled fuel while the spark plug is seated beneath the fuel tank.

Until you repair the carburetor, turn off the fuel tap. You need to clean it to prevent fuel from leaking into the engine overnight. However, it is best to turn it off after you mow the lawn. Knowing what causes a spark plug to become wet with fuel on a lawn mower engine helps you treat the machine effectively.

What Happens If a Spark Plug Gets Wet?

Engine flooding is one of the most common issues you will notice for wet spark plugs. You flood your lawn mower engine when you try to start it more than once without getting a response.

What happens if a spark plug gets wet?

When the spark plug of your lawn mower gets wet, it is highly likely to misfire. As a result, the current typically flows over an insulator as the gas/oil/fuel conducts it instead of passing through the gap.

Knowing what happens if a spark plug gets wet helps you take preventive measures so that your lawn mower becomes excessively damage. You can improve the life of the lawn mower if you take precautions sooner.

What Happens If Water Gets In Spark Plug?

When your spark plug gets wet with water, it will hinder the engine’s ability to start. Though cleaning is the best solution to eliminate this problem, there is no guarantee the problem won’t come back.

What happens if water gets in spark plug?

When water gets in your lawn mower spark plug, it gets wet. Additionally, the spark plug has the probability of getting a cracked head or blown head in the future. Most importantly, it will make the machine suddenly stop or firing inappropriately while mowing.

However, it is essential to note if the spark plug has water only on the outside surface. You won’t notice many problems until there is a loose fit between the boots and the plug body.

Should I Fix it Myself, or Take it to a Technician?

If you are already familiar with machine repair work, you can do it on your own. However, first of all, you want to figure out the actual problem of your spark plug and the best way to fix it.

You can take suggestions from a nearby local store or get some instructions for fixing it online. This could save you few bucks than hiring a professional.

However, it is well appreciated to take the spark plug to the nearby local store as they have all the necessary equipment and are professional to fix it quickly.
