:wall: I have a Craftsman (model# 917.377420) Push Lawn Mower. Mower has run fine for 12 years. Sudden problem is that it won't start, and when I pull the cord to start, it recoils every 4th time or so. When attempting to start, smoke comes out the air filter/carb air intake more than it does out of the muffler. The harder I pull, the more often and aggressively it recoils. Previous to not starting, it was running and I heard a metal clanking sound. I noticed that the blade was clanking around and was loose, so I tightened it. In trouble shooting, I have confirmed a oily spark plug, but it sparks when out & grounded and I attempt to start mower. I sand-papered the gap area and put it back, but I'll put in a new one soon. Also, the muffler is fine and the exhaust port it attaches to seems unobstructed. I just changed the oil, sucked out the possibly stale gas (we just put in before this stopped running) and I filled gas tank with fresh 87 unleaded gas (with Stabil added). By the way, the oil has been overfilled occassionally, and I suppose that is why the 2 month old spark plug is very dark all over and oily. Problem is that I hit the oil filler tube last year where the bottom of it became dislogged from the engine, and at the same time I lost the o-ring where it fits to the engine. My new o-ring doesn't seem to fit as snug and it leaks oil when running. If you have a suggestion, please offer it. Thanks for the help. :coffee: Engine model # 143.986500, engine family: VTP195U1G1SA, displacement 195.
