    Fifty2One, Thanks for the photos and data.
    I can’t tell from your photo how that clip
    is holding the handle in place. Perhaps you
    can describe?
    The one photo appears to show a grease cup
    under the magneto. Mine does not have that.

    I found out why mine has no compression.
    The piston rings are AWOL. 😮
    To compound the problem, the piston is .020
    oversize. I have not researched replacements yet.
    The piston is for a 2.020 bore, and the ring width
    needs to be 1/8".

    The crank bushings are a tad loose, but
    they have bronze bushing inserts, 3/4" ID
    x .875 OD x 1-1/2" long, so I probably
    could replace them.

    The crankshaft was fitted with some shim stock
    to tighten the flywheel on the taper.
    Any "fix" for this, other than a different flywheel?

    Is that spacer between the flywheel and rope pulley
    original?
