Cant find the dam problem 1993 gtx seadoo

[dunn6071]

Hello all I have been working on this jet ski for quite some time.
I am having isses:
just finished re building the top end.
took it out on the first day, and ran great started with choke, and idles nice, lots of bubbles from the back. looked good.
rode it hard for like 2 days. and now the machine will not start unless I give it gas, when before it did not need that.
It feels like I have no low end power, I have to push the trottle into my top end before it gets up and starts going.
when before it was sold all the way through the throttle.

Does anyone have any ideas. ????????
the next thing I am going to check it the idle screw as well as the carb timeing that joins both the carbs together.

But please any help would be great.
cheers Brandon

Welcome to the seadoo forum Brandon. Check the low speed screw that they are in sync and the carbs are tight and not leaking air. It sounds like the carbsare the problem. If it still has the GRAY fuel lines change them and clean the internal filters in the carbs.
Keep us posted on you progress.
