    I inspected all the rings via the ports when the carbs were
    removed. Poked all the rings with a plastic rod to
    ensure they weren’t stuck. Did find a lot of gooey
    carbon in the bottom of the power head and the
    exhaust leg.
    I pulled the front cover off the power head of the HS-20
    (that’s stuck) this morning. More rust than I wanted to
    see in the crankcase. Threw in in my bucket of acetone / ATF
    for now. I have a parts HD that I may try to scavenge
    parts to make one more running unit.
    Anyone ever try, or go to the trouble of planning down the
    crankcase halves and then line reaming the crank journals
    to tighten up the crankshaft fit? Not sure if it would work
    out, but just a thought!

    Prepare to be boarded!
