Welcome to the seadoo forum leechadrick. I would do a compression test first.
Here is some information on a compression test;
To test compression, remove both spark plugs. Place spark plug caps on the plug cap studs near the cylinder head to ground the empty caps. This completes the circuit of the ignition electrical system and prevents any electrical problems from the caps being un grounded. Using the correct adapter for the threaded end of the tester,( same length of the spark plug threads length)screw in the tester in one plug hole. Hold the throttle wide open. Push the start button. Watch the compression guage, when it peaks out at the most compression, let go the start button. Read the psi number. I would do it 3 times to be sure it is accurate. Check both cylinders the same way. The ideal compression is 150 psi per cylinder. If it is less, it's not a problem as long as they are close to being the same. If the psi is less than 90 it might need be time for a tear down and a rebuild. If the psi in 1 cylinder is say 140 psi and the other is 80 psi you need to tear down and repair. This difference is a lot then there is a problem. I hope this helps you.
Are the oil lines going to the rotary valve on each side of the engine? Is the injector tank still in the hull of the seadoo? Are you sure you have teh carbs cleaned properly ? Special attention should paid to the small internally filters. If it has the gray fuel lines it will need them replaced too as they deteriote from the inside out and clog the carbs. The Low Speed Screw should be at 1 1/2 turns out and the High speed screw should be at "0". it has a plastic cap on it that allows it to only be adjusted 1/4 turn out. This should help you out.If you still have a problem let us know. I'll be on here off and on over the weekend.
