I didn't want to hijack Transtar 61's post, so I'll start another. Son has a Yard Machine with a 17.5 hp B & S engine. Model 42A707 Type 2238E1 code 9904225B. It's been a hard starter for him. He said you had to crank it a long time to get it to start and if you shut it off, it wouldn't start again that day. It had a spark plug stripped out and the wrong plugs in it. I rethreaded the spark plug hole and put the right plugs in it, still no start. It has a new battery and I had him take it back and get it checked out, it's good. It cranks slow and stalls on compression stroke. I put a spark plug tester on it and it has very weak spark. I took the plugs out and cranked it over to see if it was the starter and the bendix came apart and broke a piece out of the top of the flywheel right above the teeth. Also, the new spark plug on the left cylinder has the threads on the end boogered up, looks like it's hitting the piston. Can you buy just the bendix, or just get a new starter? I'm thinking a new coil , not sure about the flywheel. Is there a do it yourself Briggs & Stratton website? How do you check the compression release? I'd like to get this fixed so I can get my extra mower back before he tears it up also. Any help appreciated. Chris
