Hmm well then let me ask this. If you went 14 years and was only at 120psi when you rebuilt and I'm at 30 hours and already at 100psi maybe I'm just not checking the compression the correct way. My shee runs like a top and fires right up after 1-3 kicks. I would think if compression was low it would be a bitch to start. So what is the correct way on checking the compression. I have a motorcycle compression tester that I use.
