Two-stroke engines are small internal combustion engines most commonly found in lawn mowers, chainsaws, and brush cutters. They have a single cylinder and run on a mixture of gasoline and oil. Gasoline provides the power, while oil provides the necessary lubrication to the crankshaft and piston. The engine can stall due to excessive priming or because the choke has been left open too far, causing an excessive amount of fuel to reach the combustion chamber. If your two-stroke engine is flooded, you can get it going with relative ease.
Place the machine on a flat surface.
Locate the spark plug that is connected to the engine. If you are unsure of the exact location, check your owner’s manual as the location may vary from engine to engine.
Attach the spark plug wrench to the tip of the spark plug and turn the wrench counterclockwise to loosen the spark plug. Once it is loose, finish unscrewing it by hand and remove the spark plug from the engine.
Deactivate the engine choke by pressing the choke control lever.
Pull the starter cable out of the machine quickly eight times while fully depressing the throttle control lever.
Wipe off any excess fuel from the tip of the spark plug, reinsert the spark plug into the spark plug hole and tighten with the spark plug wrench.
Start the engine according to the manufacturer’s instructions for that particular engine.
- When removing the spark plug, make sure your back is to the area where the spark plug is located, as fuel can be shot out when the spark plug is removed.
