    96 Seadoo GSX, 787cc

    Completly stock engine ! I'm having trouble getting a mid throttle dead spot out of this thing from about 2k to 4k rpms then it takes off, it is hard to ride in creeks because of it loading up. I have the pop off psi set at 30 on stock carbs. the carbs have been gone through, I replaced the pilot and the main jets, i have been over the adjustments over and over again. Any suggestions ?

    I just got the engine back together and it runs good on the trailer. Will take it for a light run tomorrow to see if the problem is fixed.

    well, the engine needed new pistons anyway !! The problem was my pop off psi was set too low. I raised it 8 pounds and it is alot better. Where can I get a spring kit from and some 68-69 pilot jets from. I THINK PART OF MY PROBLEM IS THAT i AM MIXING THE GAS AND IT has a little too much oil ratio at that RPM range. Everything for the injection system was removed when I bought it, too costly to add it back.
