 Not building compression 93 psi on #2 cylinder, and 103 psi on #1 cylinder.
Passed a leakdown test at 4-6% leakage.
Throttle is held WFO.
I'm lost. I've got IM heads which Cody did a valve job on. Hoyts cam. Mikuni & exhaust.
I haven't tested the boat with a load lately, but I can run 32 mph @ 4700 rpm solo. The motor seems to be strong, but is putting up shitty compression numbers.

Re: Not building compression Try that gauge on a different engine.

Procrastination is a lot like masturbation. Sure it sounds great at the time but, in the end your only f--k--g yourself.

Re: Not building compression I tried 2 different compression testers. Maybe they're both bad.
