I just rebuilt my carbs and installed all to factory specs, low speed adjuster 1.5 turns out, high speed 0 out and the ski runs great but I am having idling issues. If I set the ski to idle at 1500 on the tiny tach in the water then it revs up to 3500 out of the water. So then I turn it down to 3000 out of the water and it only idles at 1000-1200 in the water. I would be fine with the first scenario but then when I flush it out the motor wants to diesel and not turn off from idling so high. Any suggestions?

Re: 99' SPX Idling Problems
I did test each carb for the pop off pressure and they were both about the same, only maybe 1 psi deviation, but I can't remember the psi. I know the factory calls for between 36 and 40 so I guess I am somewhere around that #. Have you found success at a particular psi?

Re: 99' SPX Idling Problems
I usually use the lower end of specs I was asking because you said you were concerned about air leaks so I stated what could have been wrong for the service that you had done. pop off and pressure test as well as carb gaskets.

Re: 99' SPX Idling Problems
Bill said to richen the low speed adjusters because the engine is very lean at idle, this in turn causes the RPM's to increase quickly until the engine diesels (or glow-plugs as some call it). By adding additinal fuel via the low speed adjusters, you richen the mixture and avoid the whole scenario of over-revving on the trailer.John Kubiak
