whats up guys. alright, heres the deal. i have a '94 seadoo xp with a 657x. i got it last year for free and the guy told me that it didn't run. i put a new battery in it, replaced all the fuel lines, and rebuilt the carb. i got it out on the river last year right before it got cold just to see if it would run right. it did awesome. i only had it out for about 5-10 minutes though. so when i got it home i winterized it to include fogging it. i dewinterized it and last week i took it out on the lake for the day and it was perfect... for the first half hour. every time i had it wide open it would want to die after about 5 seconds. if i left the throttle alone it would stay running but if i kept it held in it would die. it only did this at wot. i was still able to enjoy myself with it but had to be ginger when it came to hammering the throttle. i got it back home and found that the air box wasn't tightened all the way, was missing a couple screws, and had a little water in it. fixed all that, took it out yesterday and the same problem persists but only after it was warmed up. for the first 15 minutes, all was well. what do you all think could be the problem? i also checked the fuel switch and it seems to be performing correct. i'm not an idiot when it comes to rebuilding carbs either but maybe i missed something? i don't know... i'm at a complete loss. could it be the plugs? any help would be greatly appreciated!!! thanks alot in advance.

Its fuel circulatory related. 1. Carbs need gone through. 2. The magnito side of
the two carbs has a fuel pump that draws gas, pushes thru the two carbs and
back to tank. It can't suck if the separator/filter leaks air into the supply line, or
if the selector valve is estopped with g543368((*^$#. or old gas. 99% of seadoo
problems are fuel delivery related. Read other posts.
