I am working on a 2001 Grizzly 600 my hunting club picked up for next to nothing. It doesn’t run. I have been going though it from stem to stern, cleaning grounds, cleaning fuel tank and testing everything. It needed a new starter solenoid, battery and carburetor. Just waiting for the new carb to fire it up. Compression PSI is 190. That seems high for an engine with a compression ratio of 8.5:1. I tested it with the carb removed so the engine is breathing well. Should I be concerned or is 190 psi a normal reading.
