How to Identify and Fix Common Gardening Problems ?

Why Does Your Lawn Mower Only Run With Choke On? Your lawn mower only runs with choke on because of a problem with the engine fuel-air mixture system, which can be caused by the carburetor, bad fuel, or air leaks. The choke compels more fuel in the combustion chamber to help the engine to turn over when cold.
Why would the engine only run while the choke is on or with repeated manual priming? An engine that requires the choking (partial or full) after initial engine warm up is an indication that the engine fuel air mixture system is out of adjustment.
If the engine will idle but dies at full throttle the main jet in the carburetor may be plugged. You can repair a plugged main jet by cleaning it, replacing the jet, or replacing the carburetor. If you choose to clean or replace the main jet, you will also want to clean the rest of the carburetor.
If the blades are engaged and you shift to reverse the mower is designed to either shut off the blades or the engine. Some units have ROS, this is an additional position on the key switch that can be activated if the operator feels the need to mow in reverse.
If a motorcycle or ATV only runs with the choke on, it`s because the richer “choke on” mixture is actually closer to the engine`s normal operating fuel mixture than the leaner “choke off” mixture. So when the choke is turned off, the engine gets too little fuel and too much air for it to run and it stalls.
A snowblower that runs better on half choke likely suffers from a dirty or faulty carburetor. Cleaning or replacing the carburetor will fix the issue.
Use Carburetor Cleaner

Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleanerOpens a new window, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.

The most likely culprit is a dirty or clogged air filter. Issues with your fuel pump or fuel filter can also cause your engine to idle then die with any throttle. If you have an older car, it could also be a bad carburetor.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die

By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.

The reasons why mower is not moving forward or reverse is that the battery is dead, or due to clogged fuel line. Additionally, malfunctioning transmission, or a broken drive belt, also a faulty spark plug, even when friction wheel isn`t in contact with the friction plate, or damaged Tires.
The spark plugs are worn or damaged

If you find that your lawnmower keeps dying, or keeps stalling while cutting grass, then inspect the spark plugs. Look for signs of damage or wear. Something as simple as a cracked porcelain insulator can mean an electrode has been damaged or burned away.

Chokes are designed to close off or “choke” the air supply in order to provide the proper ratio of fuel to air. An engine needs more air as it warms up, so the choke needs to open to allow more air.
A choke valve/cable is designed to restrict the flow of air in the carburettor of an engine. This helps enrich the fuel-air mixture, improving the ability to start an engine in low temperature conditions.
Manually – A manual choke is controlled by a lever on the side of the carb. A lever or knob inside the vehicle is then attached by a cable. This requires a person inside the car to slowly open the choke by hand. Automatically – An automatic choke uses a metal spring to open and close the choke plate.
If your bike is only running with the choke on, it`s probably because it`s running too lean. This can be caused by a few different things: All internal combustion engines need three things to run: fuel, air, and spark. If any of these are missing or not working properly, the engine won`t run.
To check fuel delivery, remove the fuel line where it enters the carburetor and use a length of rubber hose to direct the flow into bottle or similar container. Fuel should pulse out in strong spurts if your engine is equipped with a mechanical fuel pump (electric fuel pumps are more of a steady stream).
A clogged fuel filter is most commonly caused by leaving old fuel in the lawn mower. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the fuel filter and make the engine hard to start.
Get your can and spray the liquid on the carburettor. Make sure you don`t go overboard with spraying the liquid as it may end up harming the device. Rest assured that WD-40 is potent enough to work its magic even if it is sprayed decently on the carburettor.
When the throttle body gets dirty, it has a direct effect on how smoothly the engine operates. Signs indicating a problem include rough idling, jumpy or sluggish acceleration, poor fuel economy, and stalling. With the use of a throttle body cleaning product, the dirt and debris buildup are easily removed.
The position sensors on the accelerator pedal tell the PCM how much throttle opening to give the engine when the driver steps down on the gas.
A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
In internal combustion engines with carburetors, a choke valve or choke modifies the air pressure in the intake manifold, thereby altering the air–fuel ratio entering the engine. Choke valves are generally used in naturally aspirated engines to supply a richer fuel mixture when starting the engine.
Choking and attempting to re-start an already warmed engine will result in too much fuel and will prevent a warm engine from re-starting. If it is suspected that the engine may still be warm enough to re-start after a short break, such as less than 15 minutes or so, try re-starting it with the choke off.
Can you pull a self-propelled lawn mower backwards? Yes, you won`t cause any damage to the mower by pulling it backwards.

ANSWER : Hello. IF your spark plugs are good, and your air filter is clean, and your fuel tank is not close to empty, the next thing to check is the fuel line and the fuel filter. As a general rule, I change the fuel filter every 40 hours and the fuel line every 200 hours. J.
