Briggs & Stratton 4hp motor stalls shortly after starting?
I just serviced my lawn mower (changed plug, new oil, gas, & cleaned filter, sharpened blade). Mower will start with no problem put stalls after running for about 30 seconds. What else should I look at? The mower is a Murrey 20".
Couple things to look at.
First off be sure you didn't overfill the oil.
Second, is the gas cap clean? A plugged vent hole in the cap will do exactly what your describing.
