Jet Set Ski Wear I Have A Js550 Jet Ski Question?

I have a js550 jet ski question? - jet set ski wear

It has a Mikuni carburetor with a screwdriver and a high speed and low. I tried it in the factory settings restored, after setting the carb. It starts strong and seems to flood easily love. I had to run. I say successfully run the cards has a high compression piston / head on it and a tube for the performance. Ideas on how attitudes CARB for that?
