Hello. My name is***** first thing we need to do is a compression test.I will need the engine model number please? Just because it revs in neutral that doesn't mean anything. The engine has to be under a load to perform. The engine could be running on 2 cylinders and it will turn up rpms with no load in neutral. So that is not a test that would reveal anything.
