Each piston, but only one side at a time .
What catches out most is the inside set screw is the locking mechanism and the outer nut is the adjustment which is backwards to what most would assume is the case

I got it running. Thanks guys! Whoever messed with it last had them cranked way down! I had to back the nut off probably 4 turns on each one.

If you have NO compression reading after quickly turning over the engine, either the Rings are totally gone or valves are not closing or you have a blown head gasket.

Hello, again. If no compression on either cylinder but pistons still move in and out, what does that mean? I see what looks like fresh sealant on both valve covers? What steps should I take next? Has 142 hours on it.
Fresh sealant on the valve covers ,could be someone installed new exhaust valves & didn't set the them. Just a guess.
