    Question need help.

    I have a 1980 js440 jetski, I checked the comp. it is 160 psi for both cylinders. Is that about right for a 440 engine. One more question I have adjusted the carb. but the high side adjustment bottoms out before the max rpm. HELP

    160# is great. Sounds like the carb needs rebuilt.
