I picked up a 97 Polaris 780 a few days ago. The engine starts right up, but it has no power. When I give it throttle it simple has no power, but does not stall.
I checked the compression in all 3 cylinders and all are very good over 130 PSI. Any ideas on where to start ? I am new to Jet Ski's but have worked on outboard and cars and trucks all my life...

Thank you for you help in advance.
