    I am looking to switch out this engine with a new one because it keeps causing valve guides to on the number 2 cylinders exhuast valve. So it is only running on the the number one cylinder.

    Or if you all have any ideas on what could be causing this and what I can do to fix it that would be great to.

    the first head went so I took it off and put the head on it from one of the other machines that didnt run as good as this one and after about 6-7 lawns it was hard to start at the next lawn then when it started it was running on just the number one cylinder again.

    Thanks again for any help

    ok so I called a machine shop and am going to take it by tomorrow to see how much it will be for them to either stake it or weld it.

    But now I am wondering what is causing this.

    The fins are super clean like scrubbed with a wire brush and soaked in engine cleaner clean then hosed off.

    So any ideas on what might be causing it to overheat.

    I am just guessing that is what is happening and causing the guide to slip.

    Put a new cylinder head on it. Once they move, there is no point in messing with them. New, not used off another machine....NEW.

    Would need the spec number to tell shaft size for sure but more than likely its a 1" shaft.

    ok found a mchine shop that took care of it today for $20 dollars.

    They used a tool that etched into the valve guide and they said it wil not be able to back out anymore even if it overheats.

    They said it is a pretty common problem and had it done in less then an hour
