I am at my wits' end with my trimming mower, a little 20" $99 push with a 3.5 Tecumseh. I prime the carb, pull one time, it roars up to life and shuts down just as fast. If i continue to pump the primer or use a little starting fluid, it will run on til it burns that up then go off. I have had the spark plug replaced and checked - it sparks. I have a fuel issue, and I've had the carb off 3 times, disassembling and cleaning. Put it back together, prime, pull, same thing. Any ideas??
