If it runs that good it more than likely had more than 130 psi. So faulty tester is my guess.Awesome. No issues

The tester I have in the picture I use is an Actron and I bought it at Sears. Ive used it on boat motors, cars engines and small engines of all kinds, came with multiple adapters for different plug threads also, accurate and durable. I paid around $35 for it.When I checked compression prior to tearing it down I got 130. Piston and cyl look good.
Yes I am cranking till it stops.
Any suggestions on a new quality gauge?
Did you use a new piston ring? If not did you check the end gap of ring when you had things apart?. If your gauge is accurate maybe rings are wore a little. 20 psi bump sounds about right for a gasket delete.
Did you check the end gap of it when you had it out? If that ring is wore and the end gap is excessive you won't get good compression.It's the original piston ring
Shame you have to break it down againI'll order a new caber ring and put it in.

Just checked it again. 150 is what I got.
As far as the tester goes I bought it new last year. I have gotten a few funky reading out of it. Figured it was the O ring letting air by. Whenever I put my air compressor air gun to it, it reads close to what the output pressure says on the regulator.
That comp sounds much better and will climb a bit after a few tanks of fuel.Well I got it put back together the other day. New Caber ring installed and compression jumped up to 175. I am awaiting a exhaust gasket from the local dealership. They ordered in a head gasket on accident. I did start it up and let it idle for a min then gave it a couple quick revs. Sounds and runs great.
