I have a 98’ xp limited. The jet ski won’t rev past 3500 rpm and do more then 10mph, even when at full throttle. Then all the sudden it will jump and run normal for like 2 seconds then die back down to 3500 rpm. Also it won’t stay idling. It will just die out. Do I need a carb rebuild? I’m at a lose and just looking for ideas to try. (Also, I did rebuild the rave valves on the cylinder, but looks like there’s one on the rear muffler. I didn’t rebuild that but it still looks good)
