the holeshot is good as far as rpms go, but from half throttle to full throttle it bounces from 7000 rpm to 5000rpm about a dozen times (like its bouncing off rev limiter) and then settles at almost 6000rpm.

Tim's right - it does sound like the beginnings of a clogging fuel system.

carbs are spotless. i took the plate that the carbs mount to ( just to look) now how do i know if the thing that goes on the gear is in the right position

Are you talking about the rotary valve? if you just removed the cover not a big deal. If you removed the rotary valve itself, then you have to re-time it.
Do you have a seadoo shop manual? If not here’s an idea for you. You could join as a "premium member". As a premium member you can down load a authentic seadoo manual from the seadoo manual library. In the library is a variety of manuals for almost all years and models. You can view as many as you like on line as a PDF file, or download it and print it for your personal and private use. There are operator manuals and repair manuals for you to do your own repairs on your seadoo. The repair manuals have everything from troubleshooting, repair procedures to winterizing. It contains wire diagrams torque specs and pictures for disassemble and assemble instructions. In the spec sheets it tells everything needed to maintain oil changes, spark plug gaps, carburetor rebuilds and impeller wear ring tolerances. Click on the "Seadoo Manuals" link at the top of the page for more details. If you need any help or get in a jam, we are always here to answer your questions too. Premium members get priority when it comes to getting quick detailed answers.

yes it was rotary valve

 

[kustomkarl]

If you took the valve itself off, you have to reset it in perfect timing or it won't run. You will need a manual to help explain it. Its too involved to re-type what to do here. Re-read my post #5

[kustomkarl]

The oil injector lines to the carb?...They are real hard to blow through as they are small lines.

 

[rerested]
