1996 seadoo run away idle

[Skhrris44]

I have a 1996 seadoo gtx that i just rebuilt carbs on, genuine parts all that jazz. I have installed and now have a high idle and at times it just runs away. If i pull choke its starts to die then recovers. It seems it will idle around 3500 until i stab the gas, it revs up crisp and will fall a little then steadily climb and climb. It did not do this at all before pulling carbs off and i havent adjusted the idke screw so im not sure whats going on. Any info would be great!!

did you install new carb base gaskets when putting the rebuilt carbs back in?

 

[Skhrris44]

Yes

 

[noviceskier]

Yes

throttle cable adjusted too tight?

Dont seem to be, do u just adjust them at the bracket on the carbs??? Also does the spark arrester bulg out outwardor sink inward when installed correctly??

I'm betting the throttle cable is a touch too tight and keeping the butterflies open. Loosen it up a bit and see if that helps.

yes - adjusts on the bottom of the carb. Loosen nut on the outside of the carb and then tighten up the inside one.
