    3.0 seems low on power and dieseling at shut off

    dieseling will kill your motor. that last gasp as the motor stops is it running backwards sucking in water from the exhaust. look at your fuel quality and your ignition timing. if you have points, service them.

    How damaged are these threads.

    do you have a pipe die set? that is what i would do, start the die, cut about 2 new threads, cut off the excess length above the die, and back the die off. just be advised, your not looking at a cheap die, you will need a quality die. one that does not say "made in china"

    the engine will rev in neutral running on only 2 cylinders. that means nothing. as Scott stated, when an engine is under load, it needs fuel. my guess your carb is plugged or your anti-siphon valve is stuck.

    Can you identify this washer I found in my bilge?

    could be a fender washer from bolting in an engine mount if it is thru-bolt vs lag bolt. however the washer looks too fresh to have lived in the bilge for a while.
