    yes another low end bog question

    what the hell causes this???? went a 1/4 turn each way with the lows got worse leaner/richer

    decided to try 1/8 turn in and out on the highs no change

    what am i missing i just rebuilt the carbs and fuel pump and the thing is topping out @ [email protected]

    it pumps crazy amount of fuel
    pop offs are all right between 20 and 21

    new pto piston

    will get a look at the wash in a bit but plugs all look fairly good i've got to be missing something

    Dude, you're right there with the 6450 RPM at 56 MPH. (dam near pefect for stock)

    What are your low screws set at right now?

    What year and model is your ski?

    Is the MFD working?

    Any warnings or red lamp? Low fuel warning?

    Which model and year is this?

    mfd is golden thanks to GH it's been rebuilt and now and works spectacular

    no warnings no lights though i know they work because i saw it blink when i had them off cleaning the oil and gas tanks

    Main jet 110
    slow jet 67.5
    Hi screw M=1 1/8 C=7/8 P=1 1/4
    low screw 1 3/8
    idle in water 1250-1300 RPM
    Pop off pressure 20-24 psi


    Forget the plug chops, and check your wash. Chances are, you're missing your 50 RPM because you're too rich on 1 or more cyls.

    Rich enough to lower your max RPM though.
