95 SEADOO XP Hesitant Throttle

[95XPGUY]

I have a 95 Seadoo xp 720 that I bought about a month ago. It has good compression (145psi in each cylinder). It idles great on its own. When you give it throttle it will hesitate for a little bit (up to 5 seconds sometimes) and then boom it just takes off. Once it takes off it will run forever down the river but if you let off the throttle and grab it again it will do the same hesitation. I replaced all of the fuel lines and completely cleaned the carbs and put Winderosa Rebuild kits in. My pressure tester will only go to 30psi and both carbs must have a pop off pressure above that. I tried checking everywhere for an air leak and I can't find anything. I screwed the low speed air adjustment all the way in and backed it out 1 3/4 of a turn like the manual calls for. I can't seem to figure out what's going on.

Those after maket carb kits could definitely be your problem, they are junk. Only use genuine mikuni kits. So many people have issues with the aftermarket kits

Did you use new base gasket for the carbs?
mine was leaking from there... just in case

It's the carb kits, as said above they are absolute junk.
