What exactly is the problem?
What are the carb settings/jetting now, and what is your engine/pump setup?

Also a little history helps. Is this ski new to you, had it for years? Was it running good then you installed or modded something and now nothing? The more details you give the better we can help you.

My super jet is from second hand!!!I m riding now for a year !!!i have replace the stock CDI unit with an MSD ignition and The adjustable Rev Limiting function of the Enhancer Ingnition now is 5.500rpm!!!my carb settings now is (L)1/4 (H)1/4
I have a hesitation at the middle range and i loose the wave!!!!
i dont now the way to find the engine /pump
I m new rider and with your help i hope to learn...

If the rev limiter on the MSD Enhancer is really set to 5,500 rpm, then that is way too low.
It should be above 7,000 rpm.
What size is your main jet, your pilot jet, your needle & seat, and your popoff spring?

were can i find the main jet, your pilot jet, seat, and popoff spring!!!

I suggest you read the Mikuni manual that you referenced in your first post very carefully.
It will answer all those questions and make you familiar with your carburetor, which is mandatory if you want to get it running right.
