Lawn mowers have the amount of gas to increase from the carburetor to help kick-start the motor. One is the bulb, which, when you press it, sprays on gas directly into the carburetor. Another is the choke, which produces a richer fuel mixture and does not actually spray additional gas, but closes off the air passage to the combustion chamber. If neither of those systems is working on your lawnmower or present, you may add fuel manually. Keep in mind that adding too much gas flooding the motor.
Remove from the filter. On many lawn mowers, this is done by unsnapping some clips or unscrewing a knob.
Remove the air filter when it is dirty and clean it. By immersing it in warm water, you might wash a foam filter, but you’ll have to wait for this to dry before using the lawn mower.
Fill an eye dropper with the type of gas that your lawn mower uses. The gas should have oil blended with it at the ratio. You use to refill the tank of the mower, if possible, choose the gas.
Squirt on the gas when you removed the air filter, that you simply exposed. Try to start the engine. If the engine turns over, replace the air filter and cover.
When it doesn’t turn over following the first attempt continue attempting to start the engine. Squirt a second dropper-full of gas after six or seven tries. If another six or seven tries don’t start the engine, wait 10 minutes before adding fuel and trying again.
