    Re: crank seals, right?

    Looks like Rotary Valve Clearance. I took it apart today and found the cover badly scored. Can feel scores on the valve too.

    Testing clearance with a feeler gauge (no o ring) I was getting at least .017 clearance and probably more as .017 was going in pretty easily even while coming in ****eyed through the ports.

    Finally got a rotary cover back from SBT. Put it back together and am cautiously optimistic this was my problem, or at least a problem.

    It runs much better at stock carb settings on the trailer, will water test it tomorrow.
