If your compression tester doesn't have a valve core in the end that screws in the cylinder, it will show low compression. The Speeddway kit or the Mightyvac kit are the best for a compression tester on a small engine. If using the red Amazon test kit your compression should be ok anything over 50psi because they read low. 80psi of compression should run. I have seen engines with bad valves run with 25psi of compression. Usually under 65 psi and they get finnikey.

@amossnowdaharleyman9179 adjust the valves, the intake will usually tighten up and cause hard starting. Once started and warm they will start right up but let them cool back down and you will have to fight with it to get it started.
