There was a bulletin on that, to try to idle for a while before shutting
down. I will try to look it up to see if it gives any other suggestions.

Thanks much, I was afraid of that. Idle is actually pretty close and
problem is generally associated with shutting down after high speed
run.

Yes, on a newer unit, you should not just change timing. To check timing
requires a shunt to be used. Things that cause overrun on these are...
shutting the engine down right after a high speed run, an engine running
to
rich, adjust carb, high idle speed, and most important an engine that is
running hot.

I know this is a common problem but am still at a loss to eliminate.
Motor continues to try to run when it is shut off, which is likely a
timing issue. Can I simply unbolt the distributor cap and rotate it?
Did not look like that was possible. Any suggestions- other than
higher ocatane fuel?

I don't think you should do that. I think you should hire someone to
check
the timing for you. Check idle speed too. Engine might be running too
hot
or
too rich, carboning up etc.
