Re: 318 backfired and quit!
I was mowing two weeks ago and the same thing happened to me. Turned out that one spark plug gave up the ghost while I was mowing. Mower still ran on one cylinder but would stall out immediately under load. Perhaps the same thing happened to yours (cheap fix) and just not enough power to run the pto. Does the pto try to engage?
