    I had found a possible “sync” mark on the magneto before, but the
    throttle pin never even came close to it.
    After reading Leroy’s ramblings today, mentioned was a fast idle
    adjustment on the side of the tiller handler….. hmmmmmmmm.

    I’m feeling pretty stupid now. The knob was cranked “way in”.
    I reset it, and it looks like I’ll be able to use the mark now.

    I pulled the carb off, and came to the conclusion that I never
    had this one apart…….. perhaps it was the parts motor carb
    I was thinking of, or I dreamed it!
    Anyway, it’s soaking in cleaner now.

    The impeller was holding up the motor from turning over.
    It was pumping water great when I shut if off. As soon as
    I dropped the L.U., the motor turned over fine.
    I opened up the impeller housing, and seen no damage to
    the impeller, but it was almost like was glued in the housing
    at first. The width of the impeller appears to be “just right”.
    Not sure what to think about that. Anyone have an impeller
    stick in the housing before after sitting a few days?

    It has okay compression according to Leroy…… 68 & 69 psi.
    The spark looks great, but I’ll probably order new condensers anyway.

    Regarding the fuel pump……. The 1971 parts motor had a square fuel pump,
    part / casting number 312631.
    Will have to research that and replace the pump, or find a repair kit, if available.
