    UT2 exhaust valve stem seal?

    Tried to transfer the valve seals from my BSP head over to my UT2 head and the exhaust valve stem seal dose not fit. It is not machined for it either. Do I not run one on the UT2 head?

    What happens when valve cap falls in the motor?

    I was putting the 18lb valve springs in a predator motor and dropped the cap for the retainer. Looked every where with no luck. Even held the bike upside-down and did some shaking. Can only guess it's in the motor. Is there an easy way to check inside the motor?

    Tecumseh H60 valve seats

    How are Tecumseh valve seats removed? I'm building a hopped up H60 and want to put oversized valves in it. It seems that Tecumseh installed one insert for both intake and exhaust instead of one for each valve. Is the seat cast in or installed like a normal seat?
