    Comet clutch for 25hp engine.

    So my build I am doing a briggs flathead build that will surely put out 25hp and at most 9000 rpm and was wondering if a comet 30 series would work? Or would I need to use a 40? I just was wondering if I could damage a torque converter. Thanks you.

    How many times have you took a lawnmower motor apart and found a plastic cam? What is the chance of failure if I remove the governor and rev it? And another question. Is there a vertical shaft motor out there that uses raptor parts?
