Discussion Starter · #1 · Mar 20, 2006. Just stumbled onto this forum. I have a GCV160 engine on my lawn mower, about 5 years old, has had the same problem for 4 years. The engine starts, runs about 3 minutes and then starts stumbling, backfiring, and eventually will stall out. Cutting the throttle to idle will sometimes keep the engine.
left hand smells weird
