L82 low compression questions
Hello everyone:
Looking for advice on low compression coming out of spark plug holes.
Already have timed the engine to 8 over. Getting unsteady needle for vacuum.
Tried compression reading out of spark plug holes with carb full open. They all read 110. Manual says 150-180.
Any suggestions?
Thanks in advance.

Do the leak down test and remember that compression gauges should be used to find low compression on one or more cylinders. Sounds like you have a pretty even compression on all cylinders. Are you having a problem with your engine or just want to get your hands dirty?
