Lawn Mower Petrol Self-Propelled Will Not Start

The lawn mower won’t start

If at the first start, your new lawn mower refuses to start, try the following: based on the air temperature outside, set the appropriate position of the air damper (at temperatures less than 30 C. “damper closed”, over 30 C. half-closed position), then pump into the carburetor fuel and gently, but rather sharply, pull the starter handle until you feel some resistance. Repeat these steps in the same sequence several times. A brand new instrument must start. If this finally happened, you can safely get down to work, having previously fully opened the damper.

If the lawn mower is no longer new, then it is necessary to start its inspection from the gas tank. If the device has not been in operation for a long time, then it is necessary to drain the old gasoline, which has the feature of “running out”, i.e. lose its octane properties, and refill with fresh fuel mixture. The gasoline / fuel ratio, as well as the required grades, are usually indicated in the operating instructions for the tool.

Now you need to check the spark plug. either the problem is in it, or in the fuel system. The candle must be carefully unscrewed and its condition evaluated. If the candle is heavily flooded or there is black carbon on it, then it must be removed, cleaned and dried. Drain the excess fuel, if any, from the spark plug holes, drain the cylinder itself, then screw in the dried or, even more desirable, a completely new plug. If the plug was initially completely dry, you need to look for a problem in the fuel supply system. Check the fuel filter first. To do this, disconnect the suction hose and remove the dirty filter from it, clean it and reinstall it, or replace it with a new one. If this does not help, you should contact the service center specialists.

Will not start after winter

In this case, you just need to drain the old and possibly even frozen fuel and fill in the freshly prepared mixture. Then you need to perform the same manipulations as during the first start of the lawn mower.

The petrol lawn mower will not start. Why?

Starts up and stalls

If the mower stalls after starting, check the air filter. When this filter is heavily clogged with dust, it stops passing the required amount of air into the carburetor and allows dust to enter the fuel mixture. It is necessary to carefully remove the contaminated filter, clean and rinse in gasoline. If the air filter is clean, but the tool still stalls, then it is better to contact a professional to determine the cause of the malfunction and eliminate it.

Sometimes, after checking the condition of the mower blade or cleaning the body around the blade, the exhaust from the muffler suddenly turns black, the mower starts to “sneeze” and stall. Check the condition of the air filter. An oiled filter indicates that the mower has been tilted towards the carburetor and oil from the engine crankcase has entered the carburetor and air filter. Therefore, always tilt the mower away from the carburetor when cleaning or replacing the blade. either towards the rear wheels of the lawn mower (see video).

    • fuel line malfunctions,
    • clogged air filter,
    • gas tank plug valve does not work,
    • incorrect position of the air valve,
    • spark plug does not work,

    Lawnmower Will Not Start. Causes of Malfunction

    A petrol lawn mower may not start for three groups of reasons:

    • power system malfunctions;
    • malfunctions of the ignition system;
    • problems in the block of cylinders.

    The mower will not start due to poor fuel supply

    When your petrol lawnmower won’t start, the first thing to do is to check for fuel in the tank. If it is absent, add it to the required level.

    Another very popular option for the lawn mower engine not starting is a problem with the gas tank plug valve. If the valve is clogged on it or does not work, then the pump simply cannot pump fuel.

    The mower may not start if the position of the air flap is incorrect during the first start. Depending on the air temperature, it is completely closed or set to the middle position (above 30 C). Then it must be fully opened.

    The lawnmower may not start if the air filter has poor air flow due to contamination. To fix this problem, you need to remove the filter and clean it. If the filter is heavily soiled, it must be replaced.

    A common reason for the inability to start the mower engine is a problem with the carburetor, most often it is simply clogged with dirt and the remains of low-quality fuel. It is necessary to flush the carburetor and adjust the fuel mixture supply.

    Lawnmower will not start due to poor ignition system

    Another reason your petrol lawnmower won’t start could be a faulty spark plug. The spark plug must be removed. clean it and adjust the thermal gap.

    A frequent breakdown leading to problems with starting the engine may be incorrect starter operation. It is necessary to check the correct position of the starter, the correct winding of the cable. Make sure that the starter provides voltage during operation.

    How to start a lawn mower when the engine stalls at home

    It is especially difficult to start the mower after a long period of inactivity. What should the user do when the sado-technician refuses to work:

    • If the device has not been cleaned for a long time, you need to flush the air engine, it is cleaned with gasoline (it is advisable to do this every 24 hours of operation). You can remove the filter from the device and start the unit, if the mower is working, then the reason lies precisely in this.
    • After winter, the remains of old gasoline in the tank can interfere with the operation of the device. The problem is easily eliminated if the fuel is replaced with a new one.
    • An insufficient amount of oil in the crankcase can also be the reason why the gasoline lawn mower will not start. Check its presence, whether there is fuel in the tank.
    • Incorrect position of the air damper during the first start. At temperatures ≥ 30 C, it should be in the middle position or closed. On restart. open.
    • Jamming of the crankshaft, piston. can be eliminated by slightly moving these parts. The main thing is to do it carefully so as not to break the mechanism.
    • Dirt in the breather. the fuel supply stops, you need to clean the part.
    • Dry threaded connection. with this factor there is no ignition spark, lubricate the connection with gasoline.
    • Spark plug malfunction. accumulation of oil on it, plaque. The candle is unscrewed, dries well, cleaned with a nail file. Excess fuel is drained, dried for at least 30 minutes. candle hole. Part may need to be replaced if it cannot be cleaned.
    • The contact of the high-voltage wire and the candle is also checked for the presence of a spark. If the latter does not occur, the malfunction of the ignition system will be identified and eliminated only at the service center.

    The structure of a gasoline lawn mower

    Before you repair the device, you need to figure out what it consists of. There are many models of garden equipment from different brands: self-propelled, non-self-propelled. They all work the same way. The constituent elements of the structure:

    • platform on wheels;
    • gasoline engine (starter, carburetor, ignition and fuel supply system, air damper, filter, piston system, fuel tank.);
    • manual handle;
    • water jet nozzle;
    • cutting elements (knives);
    • grass collector (container);
    • unit for throwing out freshly cut grass;
    • buttons, control levers;
    • body (aluminum, steel, plastic).

    Prevention of malfunctions

    The rules for operating garden equipment are not complicated, if you adhere to these points, the device will last longer than the expected period:

    • Always use a good quality fuel mixture.
    • Do not work in the rain.
    • Prime fuel to carburetor.
    • Pour the required amount of gasoline into the tank, exclude fuel from entering the engine.
    • Mow intermittently. Give the device some time to cool down and rest. The petrol lawn mower will often not start when hot.
    • Clean the complete set of the structure only after the engine has cooled down. Should be cleaned: knives, channels, filters, container. It is advisable to do this with the use of special cleaning solutions. this way it will be possible to avoid corrosion of metal elements.
    • Store the device in a dry, warm room, eliminate moisture ingress.
    • In the course of work, do not put pressure on the device, make smooth forward movements, move along the site. Chaotic back and forth movements. wear out the unit faster.
    • If the device is not used for a long time, you need to replace the fuel with a new one. Gasoline stagnates in the system, does not allow the unit to function normally.

    It should be noted that with the onset of cold weather, the car is removed as unnecessary, it is recommended to drain all gasoline for this period (it is explosive during stagnation). How to properly prepare the mower for work after winter: inspect the entire body for defects, drain and replace gasoline, check for oil, start the machine for the first time with the air damper slightly open or closed.

    Symptoms of problems

    The first thing a user can notice is a deterioration in the quality of the device. The grass is not mowed evenly enough, leaving missing spots on the lawn. This happens because the motor starts to junk, its power decreases. TOP 5 symptoms indicating a problem:

    • Increased vibration of the device.
    • Increased operating noise.
    • The lawnmower starts and stalls.
    • The device turns off by itself.
    • Car whistles.

    The main 3 reasons why the lawn mower stalls are improper operation, overload, prolonged operation (engine overheating). The system is cooled down thanks to the air filter, it should be checked every time you use garden technology. What to do to prevent the mower from stalling. before turning on the device, check the presence of gasoline in the tank, whether there is oil. It is recommended to clean the filter after each mowing.

    Troubleshooting by professionals

    The service station is not only for the car, but also for the garden technique. Usually, a service center is contacted in the event of a piston and carburetor malfunction of the device. Why and why the gasoline lawn mower does not start in these cases is determined by the master:

    • Damage to the integrity of the device or individual parts. with a tonometer, using pressure, find the affected area, seal it.
    • Clogging of channels, nozzles. elements are blown with air, cleaning fluids are used.
    • Worn pistons, gasket. replace the assembly part.

    Why the lawn mower won’t start, reasons

    You can figure out what caused the device to malfunction by disassembling it. This must be done carefully and carefully, there are many small parts inside that are easy to break. There are 2 types of damage: mechanical, electrical. Let’s take a look at the most popular reasons why the mower won’t start and stall:

    • the carburetor is out of order;
    • bolted connections loosened;
    • breakdown of the motor;
    • the moving components of the mechanism (crankshaft, piston) are jammed;
    • blocking of the cutting tool (cylinder) with a foreign object. branches, sticks, hard grass, stones, etc.;
    • the oil and fuel supply system is broken;
    • the spark plug is out of order;
    • stretched, belt broke;
    • small or too large clearance between parts inside the structure;
    • faulty switch of the device;
    • dirty fuel hose, ventilation grilles;
    • clogged air filter.

    If you use the petrol lawn mower for a long time without interruption, the device will stall. Why does the lawn mower stall and not start hot? Motor overvoltage occurs. It is better to postpone mowing, let the lawn mower stand, after it has stalled, most likely the reason lies in the overheating of the device.

    Why the lawnmower won’t start?

    Features of using garden equipment

    It should be remembered that the grass can be mowed no more than 20 cm high, 1/3 part at a time. Always switch off the machine before changing the bevel height. You need to work especially carefully on slopes, move along the terrain.

    So that foreign objects do not get stuck in the blades, before mowing, inspect the area for stones, sticks, anything that can interfere with improving the lawn. If, nevertheless, the device is jammed, unplug it and check the knives for anything extra.

    What to do if your petrol lawnmower won’t start

    The main thing in the use of any garden equipment (and equipment in general) is compliance with all operational requirements, as well as timely maintenance. Only under these conditions will the petrol lawn mower work properly and for a long time. However, unforeseen situations do happen, and one “fine” day the device may stop starting. Today we will find out why this is happening and how you can fix this kind of problem.

    Common breakdowns and how to fix them yourself

    If the mower does not want to start, then first of all check if there is any gasoline in it. If not, top up to the required level. The fact is that if the device is idle for a long time, the gasoline is “exhausted” from it, therefore, it must be drained and replaced with a new one. Do this carefully so that fuel does not get onto the engine (otherwise it may ignite).

    Note! If you do not know which gasoline should be used specifically for your lawn mower model, find the relevant information in the technical data sheet.

    By the way, if you are just planning to buy a gasoline lawn mower or any other garden equipment, we recommend visiting gardenmoto.ru. There you will find a wide range of products at very reasonable prices. But back to the reluctance of the device to start.

    So, the next reason why a similar problem may arise is the incorrect position of the air damper when making the first start. Based on the air temperature, this damper either closes completely or rises to the middle position (if the temperature is 30 degrees). After that, it should be opened entirely.

    We also recommend inspecting the air filter to see if it is dirty. To do this, turn on the mower and disconnect the cable from the spark plug. Remove the cover, remove the filter, wash it with gasoline and dry it thoroughly (or, alternatively, put a new one).

    Note! The air filter should be replaced on average every 25 hours of use. Remember this!

    Finally, the last reason is a faulty candle (by the way, it might just be filled with gasoline). To find out, unscrew it, clean it and check for a spark. Next, close the choke and try to start the engine. If this does not work, you better trust an experienced professional.

    As a result, we also recommend that you regularly study the lower part of the mower, as damage to it can be the reason that the engine will not start. That’s all, good luck!

    Faults that you can fix yourself

    When your petrol lawnmower won’t start. first of all, it is necessary to check the presence of fuel in the tank. If it is missing. top up to the desired level. Often, when the device is not used for a long time, gasoline “runs out”, so it must be completely drained and refilled with new. This procedure must be done carefully so that fuel does not get on the engine, as this can lead to further ignition (when the engine heats up). Which gasoline is better to use, you can find out from the technical passport of the device.

    In order for the unit to start, you need to pump fuel with a primer (if available in this model) into the carburetor and set the maximum speed. You need to start the technique carefully. The starter cord must be smoothly pulled out until it stops, then pull it towards you with one even sharp movement.

    A problem can occur if the air damper is not correctly positioned during the first start. Depending on the air temperature, it is completely closed or set to the middle position (above 30 C). Then it must be fully opened.

    Check the air filter for dirt. To do this, turn off the machine and disconnect the wire from the spark plug. Unscrew the cover and remove the filter. Rinse it with gasoline and dry it thoroughly, or simply replace it with a new one. Remember that it is recommended to change the air filter after every 25 hours of operation.

    Another reason your petrol lawnmower won’t start could be a faulty spark plug. Perhaps she was just flooded with fuel. In this case, unscrew it, clean it and check for a spark. It may not be present when the spark plug is filled with fuel. Move choke control handle (if equipped) to the CLOSED position and start the engine. If this does not help, it is better to seek help from a specialist.

    Try to constantly inspect the bottom of the machine, as any damage to it may cause the engine to stall.

    If your petrol lawn mower started up normally but stopped working almost immediately, it is likely that the crankshaft or piston is stuck. Another reason may be insufficient oil in the crankcase. We recommend manually moving these parts and checking the oil level with a special dipstick, you may be able to correct this problem.
