Compression test didn't show anything: 1-120, 2 through 6 had 130 each so that seems good to me.

Hope you got these numbers with a cold engine and not holding throttle open.
Don't mean to alarm you but those numbers (although fairly consistent) seem a bit low.

Engine should be at normal operating temperature when doing a compression test and throttle s/b held wide open during cranking.
This would bump up your numbers when you do this.
I would shoot for 150lbs for a healthy engine.

Best way is to do a leak down test in conjunction with a compression test....this will tell all.

Sorry........double post.

Sorry, yes it was cold and throttle was closed. Didn't start the engine at all before doing the test. I did allow the guage to stay installed a couple minutes on each cyl before reliecing the pressure. Nothing leaked down during that.
