How to change a lawn mower carburetor?

A carburetor is the core element that keeps your Lawnmower running strong and perform better. The lawnmower carburetor ensures that the proper mixture of fuel and air will enter the engine cylinder for combustion. When ignited by the spark plug, the fuel and air mixture will combust, forcing the engine piston downward, which rotates the crankshaft causing the lawnmower blade to spin and the lawnmower wheels or riding mower wheels to turn.

The most censorious component for the functionality of a Lawnmower is the carburetor. If the carburetor is clogged with dirt, it has water damage, debris, gummed-up gasoline, rough engine running, running rich, stalling, and many other problems. Replace a damaged or restricted riding lawn mower carburetor with a manufacturer-approved replacement part.

If the carburetor is not beyond repair, you can rebuild it instead of replacing it.

Steps To Follow:

The steps mentioned above will undoubtedly help you get familiar with mechanical components and save your time and cash. Do not worry, as we promised; we would discuss every step individually.

Step 1. Unhook the wire within the spark plug:

Firstly, you have to disengage the primary spark plug wire. Probably the most important safety precaution that you can take when doing your repairs or maintenance on a lawnmower is to disconnect the spark plug wire before you do anything else.

Merely follow these simple for the segregation of ignition wire. Disconnect the spark plug. Then, remove the rubber “boot” that connects the spark plug to the wire. In the end, make sure to turn it, so the back of the boot is facing the spark plug. Another prime concern is that you must be working in a well-ventilated area to prevent any property and self-damage.

Step 2. Bring out the air filter housing:

Secondly, you have to detach the air filter casing. Then, unbolt the screws and pull the air filter cover off. After that, take out the air filter. At that moment, unfasten the screws from the base of an air filter. Lastly, release the breather tube, and then last but not least, pull off the air filter base.

Step 3. Drain the fuel tank:

Next, you have to drain the gas tank. First, place a shop rag or piece of cloth under the fuel tank to catch the dribbled out fuel. Then, place a fuel-safe container under the gas line connected to the fuel tank. Farthest away, release the spring clamp and separate the fuel line from the gas tank. This is how you drain the gasoline into the container. For cleanliness during your work, it is better to wipe up any fuel drizzles promptly.

Step 4. Remove the blower housing:

Then, disengage the outer blower casing. The following steps will help you to disengage the casing. At first, you have to dispatch the starter rope from the main handle of the mower. Afterward, unfasten the screws from the outer blower casing, and the next step is to take off the engine’s blower housing.

Step 5. Remove the carburetor:

It is recommended that you record a video during this procedure or take some photos of the assembly after every step to be easy for you to install the new one on the same procedure.

Firstly, separate the carburetor mounting bracket arms to release the carburetor. Carefully disassemble the screws and jets. Now, disconnect the carburetor from the carburetor adapter. Then, grasp the carburetor above the bracket and disconnect the main lines that govern the carburetor’s functioning. At that point, remove the choke linkage rods, remove the carburetor, and then release the fuel line with a spring clamp. Last in order, pull the fuel line off the carburetor.

Step 6. Install the new carburetor:

Initially, push the O-ring into the outlet port of the new carburetor. Then, install the retainer on top of the O-ring. Now, Connect the fuel line to the new carburetor and secure it with the spring clamp. You have to hold the carburetor over the mounting brackets, connect the governor, and choke linkage rods. Later, push the carburetor into the bracket arms and fully push the outlet port onto the carburetor adapter. In the end, push the air cleaner gasket into the channel on the carburetor inlet.

Step 7. Restore the blower housing:

Reconnect the blower housing by following the steps below:

• Step 1: Set the blower housing on the top of the engine and line up the mounting holes.
• Step 2: The blower housing mounting bolts and screws must fit tightly to maintain the balance of the whole assembly.
• Step 3: Re-join the starter rope to the handle of the mower.

Step 8. Attach the fuel lines to the tank:

Push the fuel line onto the tank fitting and secure it with the spring clamp. It would be best to be cautious in connecting the fuel lines so that no fuel leakage occurs.

Step 9. Reinstall the air filter casing:

The following steps will help you to reconnect the casing of the air filter.

Position the air filter base on the front of the carburetor and reconnect the breather tube. Secure the air filter base with the mounting screws. Reinstall the air filter. Position the air filter cover on the front of the base and snap it into place, engaging the locking tab.

Step 10. Affix the spark plug wire:

Push the spark plug wire back onto the spark plug. The whole assembly is back in its original position. Now it’s time to run your mower to check whether the system functions up to the mark.

Frequently asked questions:

How do I know if my lawnmower carburetor is terrible?

Some symptoms are showing that your carburetor is full of dirt, dust, and debris.

• The lawnmower engine has trouble starting.
• The engine starts but stalls while you are cutting the lawn.
• The engine runs rough during mowing.
• Black smoke is seen coming out of the muffler.
• There is a noticeable increase in fuel consumption during everyday lawn mower use.

Can you clean a carburetor without taking it apart?

You can clean the outside of the carburetor without disassembling it, but the critical stuff to clean is on the inside, and for that, it must be disassembled not all the parts but the outer casing at least. Buy a good quality carb cleaner that is an aerosol spray. Clean all of the passages thoroughly with it. This is how, without removing the carburetor, you can clean your dirty, dusty and carburetor with old grass and debris.

Is it better to rebuild a carburetor or buy a new one?

In my opinion, it is better to rebuild a carburetor rather than replacing it. The internal parts like spark plugs, choke linkages, fuel lines, and head gaskets maybe weakened and crumble, which in return cause multiple problems. Besides, the gas that sits in the fuel bowl can deteriorate and start to vanish parts inside the carburetor. So it is recommended to replace only the defective parts timely. Some replacement carburetors cost 400 to 600.

Final Remarks

A carburetor ensures that the air-fuel mixture in the appropriate proportion is supplied to the engine that ignites in the cylinder to drive the piston. Like all other devices and machinery, timely care and maintenance of mowers can prevent any major or critical issues. The tuning and cleaning of vital parts are recommended timely. In severe cases, defective parts must be replaced well in time to prevent the abruption in the mower system. Proper maintenance and preventive measures enhance the life of the components, their functionality, help our machine work properly, prevent corrosion, and save costly replacements. Its care decides whether our Lawnmower will provide service for years or fizzles early. If you find that your current Lawnmower’s repairing and maintenance will be expensive, you should better invest more and get yourself a new lawnmower.

Introduction

Solve most lawnmower or other small engine starting problems with a simple diagnosis and a carburetor cleaning or rebuilding. It will only take a few hours, and you’ll avoid the minimum 80-plus-parts repair bill.

Materials Required

If you can’t get a small engine started, it takes too many pulls to get it going, or it runs poorly, ask yourself this: Did it sit for a long time with gas in it? Like over the winter?

Draining engine oil is so 2017.

The engine modifications and new technologies are in. The re-envisioned oil filter with a media designed to resist breaking down in oil over time is here. The thousands of hours of testing are done. The end result is an all-in-one, oil and oil filter system like no other. The first of its kind. And thanks to the new John Deere Easy Change™ 30-Second Oil Change System (“System”), you’ll never have to drain the oil from 100 Series Riding Lawn Tractors again.

Here’s why: The new System captures contaminants and recharges your engine with nearly a quart (0.8qt) (0.76 l) of new oil. In fact, this System increases the amount of oil in the engine by nearly 40%. 2 Your engine likes that.

What do you mean, I will never have to drain oil from my engine again? How is that possible? The answer is simple. We have developed a better filtration system and filter design for our 100 Series Riding Lawn Tractors 1. This fully synthetic filter media has greater surface area which increases its capacity to hold harmful contaminants. What’s more, the filter media is designed to resist breaking down in oil over time. Which means you’ll get a cooler running engine. And a cooler running engine and better filtering helps increase engine oil life. John Deere’s recommended oil service for 100 Series Riding Lawn Tractors 1. is to change the System every 50 hours or once a season, whichever comes first. Remember, the System replaces a portion of your engine oil. And that’s plenty.

The System uses John Deere Turf-Gard™ Oil. Using John Deere Turf-Gard™ Oil ensures you are using the exact oil specified by John Deere engineers.

Testing. Testing. Testing. Thanks to thousands of hours of rigorous and extensive testing, you can feel confident your engine will run for years to come.

1 The John Deere Easy Change™ 30-Second Oil Change System is available on E120, E130, E150, E160, E170 and E180 Lawn Tractors today.

Frequently Asked Questions:

What is new with John Deere Riding Lawn Equipment?

We are excited about the exclusive John Deere Easy Change™ 30 second oil change system. Exclusive to John Deere and only available on certain models of the new 100 Series Lawn Tractors. These tractors are designed for ease of use for both operation and maintenance. The John Deere Easy Change™ System (“Easy Change”) allows the user to easily complete the recommended engine oil and filter maintenance in 30 seconds.

What is this new oil change system?

We changed the oil change. The all-in-one oil and oil filter system gives the owner the ability to change a portion of the oil and the filter in less than 30 seconds.

What happens to the rest of the oil in the engine when the Easy Change system is replaced?

The Easy Change system replaces.8 quart of oil. The remaining oil in the engine is refreshed by the charge of new oil included in the replacement Easy Change system. Combined with 40% more engine oil capacity, improved filtration and cooler running temperatures which help extend oil life, it is no longer necessary to remove and dispose of all the oil in your engine during service.

What makes the Easy Change system unique from other filters?

It is not just a filter. It is a newly developed technology system that allows a new “filter” to come already charged with oil and allows you to remove an existing filter and the contaminants inside without tools and without making a mess. Beyond the filter, technology within the canister and on your engine makes this possible.

Models with the Easy Change oil system use a fully synthetic filter that has more capacity to trap and hold contaminants. The larger surface area of the Easy Change canister acts like a radiator helping the oil to stay cool.

Does the Easy Change system somehow decrease the life of the engine?

The John Deere 100 Series lawn tractor models, with and without Easy Change, are specified for the same lifetime and are rigorously tested to the same standards to ensure the life of the tractor meets expectations.

Can I add the Easy change system to an existing tractor?

Because this system also requires unique features within the engine, the Easy Change system cannot be added to an engine that was not equipped with it at the factory.

Can I change all the oil if I choose to?

You could if you wanted to. There is an oil drain plug. It is not required for maintenance.

How often do I need to change the Easy Change canister?

Every 50 hours or once a year. The 100 Series Lawn Tractors with and without the Easy Change system have the same maintenance schedule.

What type of oil is recommended?

We recommend only John Deere Turf-Gard™ 10W30 Oil. The Easy Change canister comes pre-filled with John Deere Turf-Gard™ 10W30 oil.

How do I recycle the old oil?

Many local government recycling programs, authorized retailers, auto repair stations, and auto parts stores will puncture and recycle used oil filters and oil.

Do I ever need to add oil?

Yes. Consistent with our service recommendations for this product, you should check oil level daily and add oil if required.
