I have an OS XZ Speed engine that has just over 2 gallons on it. It has been well takes care of and comes with everything pictured. Compression is still good. It passes the 3 sec test.

Not sure where it came from but it is when you hold the flywheel and let the engine sit on its side in the air. If 3 seconds pass before the engine goes through the compression stroke then it passes. This engine actually takes 7+ seconds. Some OS guys will say if its under 3 seconds then its time for a pinch. I have seen OS engines run great with very little compression so IDK, but thats the test and this engine has great compression.

I've always thought that as long as an engine can hold its position, compression is good. Didn't think of counting for more than 3 sec..
Anyway good luck for your sale!
