I've got a 2001 Craftsman LT1000 with the B & S 16.5 hp engine. When I bought this mower in May, 2013, the previous owner had just put a new starter in it. Within a few weeks after I bought it the engine started to either turn very slowly & suddenly speed up & start or "clunk" like the starters not turning the engine. After several tries it would start. It only did it a few times until I parked it for the winter. This year it's gradually gotten worse to the point where it won't start some of the time, only "clunk" like a bad starter. A couple days ago I pulled the starter & battery ( 2 yr. old diehard) & took them to Napa. They both came out as being good. I then replaced the solenoid & it still makes no difference. It either turns very slowly & suddenly speeds up or "clunks" like a bad starter. Where do I go from here?:confused3:
I Have the same issue I pulled the Spark Plug and the engine turns over fine . Put the plug back in and it only turns the motor by about a 1/4 of o turn, We have installed a new Battery and a new starter. Maybe someone will chime in with a solution.
I agree with Rivets on valve adjustment. I believe there is a compression relief built into the cam/valve train and if not properly adjusted, results in the starter not being able to turn the engine over as it should. gregjo1948

Classic valve adjustment issue. There was a point a few years ago where I could diagnose a valve adjustment issue over the phone, nowing only the model number. if the model number started with 3137 it would need the valves adjusted.

I don't know the difference between the 3107 & 3137. I do know on 2 different Briggs, in the past month and a half, that wouldn't turn over, it was due to the wrong valve adjustment. gregjo1948

I finally found the time to adjust the valves & it starts right up. Thanks so much for the help. :drink:
