01 Challenger 717(x2) pop off spring weight?

So that would make my pop off 43 psi according to (mikuni’s graph) instead of 36-40 which could be why i might be having trouble because the boat will "bog down" at point of 3/8 throttle in slow acceleration but if you go to WOT from idle, it will jump to full speed. The 80 gram should put it at 38 right? Or could i be looking at the wrong issue here
The issue is that people get hung up on pop-off.
It is only a test and has nothing to do with the actual operation of the carbs. You should be within the range and both carbs should be the same. The Mikuni chart is more accurate than the seadoo "range".
Do not change springs to chase pop-off. If your model calls for 95 gram then you use 95 gram and pop-off should be close to the Mikuni spec.
If you are having issues at 3/8 throttle it is more likely your transition holes on the inside body of the carb.
