You may have leaking crank seals. If they leak they can cause air to mix with the fuel before it gets to the carb, causing the motor to rev high unexpectedly.

It has caused damage to the electrics take it to the dealer for repairs.

the oil injection unit on these skis can fail to test you will need to empty gas tank disconnect oil feed line to inlet manifold
then make a mix of two stroke fuel to the correct ratio say 10 liters. poor in to tank and take ski for a run say 10 minutes let it rest and run again if problem persists

it is possible you have leaking or blown crank case seals you will most likely need a professional to test for
i have provided you a link for free shop manual

You might want to post this question in a different section. This is the computer games section.

I had a similar experience with that model. It turned out to be a mouse nest in the water box. However , in this case i think you just have some moisture corrosion on the rubber tipped needle in the carburetor. Clean that part of the carb and do not alter the tiny spring in any way. If that does not work open the electronics box, if it is wet , dry it out , and seal it back up. Those are the three things I know of that will cause your problem. Start with the carb.

2003 kawasaki stx-12f jetski wont start.
