Yes, it can be replaced or removed and milled down. It is a simple alum.
alloy spacer ring designed to accommodate different requirements for coarse
pitch blade angle. Yes, the cylinder is fine. I can't be certain this is
your problem but it sure fits the symptoms.

Walt, thank you. I had not heard/known about this difference in piston ring
size and will look to see. If I open it and find that the ring is the
Chinese 8mm size, can I replace it or mill it down to 4mm or do I need a
replacement piston? I assume the cylinder does not need to be replaced.

That is a stock M14 ring. The course pitch will be approx. 35 deg. so back

It has nothing to do with the high RPM (99%) adjustment.
The 53% setting could, I believe, be obtained with adjustment of the
governor low RPM screw even with a higher coarse pitch setting in the prop.

Jon;
I replaced all of my instrument screws years ago (with flush #6 AN stainles
s) but pretty sure I still have all the originals in a bag.
This is instrument screws only, not panel mount or CB=99s etc.
No charge unless I have to pay a Trump tariff to mail them to you from Cana
da.
