Most of the tightness was a result of burs at the top inside of the sleeve. The engine would not have turned through top dead center without excessive force.

It has been fixed by a little time with fine emery and steel wool. I elected to fix the engine simply because I know how and it was easier than returning it. Inspect and clean was important. The engine looked good in all other respects.

The engine had not seen fuel and showed no signs of disassembly. It had a small squirt of lapping compound after final assembly. One might guess the burs were created when the cylinder was tumbled for cleaning.

Bax, thanks for the concern.

Tower was business like and prompt with the order and did all the correct things.
