I am having trouble getting the watercraft to go past 1/3 throttle, just bored over new pistons and rings so compression is good new plugs, starts great runs great just won't go over 1/3 throttle. It has west coast pipe and head. Any suggestions would help 1993 seadoo sp, thank you

Carburetor pop off set to high? Not allowing needle and seat to open completely. -

I have the pop off at 19 on each of them, how can I measure the vacuum off the motor, I also have a aftermarket rotary valve, would ther be anything with the timing?, thank you for getting back. Also what kind of compression gauge do you recommend to buyComment

Re: 1993 seadoo sp
Rotary valve timing could be off. Did you have it out? If not it would have to "jump" time. Meaning a rotary shaft gear going bad. We use Snap on gauges here, but Craftsman or other good name brand should work fine. I don't know what you trying to measure vacuum for.Comment
