    Were going to need more info. How long have your had his ski. When was the last time the carbs were re built stuff like that, also include anything you have done to the ski.

    6200 RPM is about right. Whats the RPM at idle? Will it stay running if you throttle up at all? What year SL 750?

    Just bought ski off craigs. it's a 94 and it will stay running just barley touching the gas. the Rpms are around 100 then drop arond 80 and dies when not touching gas at idle seems to run good otherwise. It has the sbt fuel pump I think the autocock is off one of the fuel rails has a plug in it is this ok or right ?

    I would replace the fuel pump with the triple outlet version. Contact John Zigler @watcon for a kit that has everything you need. The idle issue may just be the idle speed needs to be set.

    Idle should be more like 2000 not 100, adjust your screws. Just bump the screws enough to keep it running now and then when you can set it in the water set the idle at 2000 or so. You cant set it out of the water it wont turn out right.

    Idle speed should only be around 1300 RPM

    Not knowing the condition of the ski from the previous owner, i would do all the recommended fuel system upgrades.(fuel lines, fuel pump, petcock, carb rebuild)

    See what you get then.

    And yes, the idle should be around 1200 RPM in the water. On the trailer it will be around double that because there is no load on the engine.

    K thanks guys where's the idle screw at and when it's at idle I hear a clunking/ticking sound but when I give it gas it goes away ? Fuel lines look newer and it has the sbt supplemental fuel pump does anyone know about this pump and will it do the job ?
