Your Briggs and stratton lawnmower starts but then cuts out after about 30 secs What is wrong with it?
The fuel filter is probably clogged and restricting the fuel flow. If the engine blows black smoke before it cuts out, then the engine is flooding - look for a dirty air filter or a fouled spark plug.
Why is the spark plug black on a Briggs and Stratton?
The fuel mixture is probably set to rich. Also, the wrong spark plug (with regard to heat range) could be in the engine. If you have an adjustable carburetor with mixture adjustment screws, try turning the screw (probably located on the bottom of the carburetor, in the middle of the bowl) inward 1/8 to 1/4 of a turn. This will lean the mixture. If you have a no-adjust carburetor, then there is not a lot you can do to change the mixture. Try using/replacing the spark plug with the correct spark plug as recommended by B&S. Good luck!

Why wont your Briggs and Stratton 4 point 5 hp mower engine not start after removing and reinstalling flywheel cover?
check to see if it is getting spark . you probably have the "kill mechanism " installed wrong . It's probably grounding out the ignition system. The "kill mechanism" is the cable operated mechanism that goes from the handle with a cable to the pull start housing . Its either improperly installed or out of adjustment.

Why does a Briggs and Stratton 4.5 HP lawn mower engine stop 2 3 seconds after it starts unless you continue to prime it?
it is losing its prime... i have the same problem right now and i have cleaned the carburetor, changed the gas and spark plug and changed the air filter. The only thing that i can think of is that there is something wrong with the priming bulb or the gas cap is hindering the air flow... still trying to repair....
