Briggs and Stratton lawnmower engines are among the most revered engines for garden appliances. It has been making small engines for garden use for more than 100 years. But like any other machine, there is always a chance a Briggs and Stratton lawnmower engine won't start up immediately. Be it the cold weather or just a tough day in the yard, there are a few things you can do to get your Briggs and Stratton lawnmower engine to fire up again.
Look for any obvious damage or missing parts on the engine. A missing oil cap or gas cap can indicate fluid loss. A disconnected spark plug will prevent the engine from igniting the fuel. Damage to the carburettor or engine could prevent the combustion process from working. A broken starter or damaged starter cord will keep you from getting the engine to rotate.
Check your fluids to see if they are at appropriate levels. If you recently put oil in your lawnmower and it started to smoke the last time you used it, chances are the oil flooded the engine. This can happen if the lawnmower is tipped over for a long period of time. Top off your oil, start the lawnmower and let it run until all the smoke is gone.
Ensure your engine does not have compression lock, which is when air becomes trapped inside the engine. This will prevent the starter clutch from rotating the engine fully, preventing you from getting a full pull on the cord. If this is the case, loosen your spark plug and rotate your engine blade to release the air. Replace the plug and try to start the lawnmower again.
Examine the spark plug to see if it needs replacing or is firing incorrectly. If the plug appears to be fouled with dirt on the tip, wipe it off with a rag. If there is too much debris on the tip or it appears burnt, replace the plug.
Clean your lawnmower after every use.
Do not use gasoline to clean your engine. This could result in unintentional combustion, posing a risk to you and your surroundings.
