Answer 1

OK, this is beyond diagnosing over the net.  If you can afford to put fuel in that gas guzzling pwc, you can afford to take to a shop.

Answer 2

I also agree with jim s, configuring your carb must be done with with a professional who knows how to set it correctly.  You simply don't have the experience or the information to do it correctly.  Additionally, I believe the idle and high speed throttle settings have to be done under a load or under certain RPM ranges specified by OEM requirements.

Well look on the bright side by taking it in to get the carb configed and serviced, if you've done the carb and primer installation right, you've saved yourself some labor costs.  If not, well you'll be doing the smart thing in getting it done right.

You gotta pay to play for boats and PWC's.  Even a penny pinching person like me can't get around that.

Answer 3

the carb itself may need tuned to your jetski engine[air/fuel ratio etc]...it may also be a spark plug braking down or a faulty coil...
