If you used a lot of oil when you put it together that can cause a high compression issue.
There are lots of Asian automotive compression testers that use 2 hoses the first connects to the guage and has the Schrader valve and then a second hose that adapts the plug thread. Not good for small engines as they always read low.

92cc engine with advanced timing. You need to pull it like you mean it.

They make guages expressly for small engines.
