I have always done my compression tests by continuing to crank till the needle stops. Throttle bodies should be full open. But I really don't have that much experiance with 2-stokes. You should also consider a leak-down test. I don't take any one test or reading as gosphel. I look at all the evidence and base my descision on all the facts as I understand them.
