    Another carb removal headache

    right lets break it down

    ski - 1994 polaris sl750

    problem - running intermittently on 2/1 cylinders

    things i have tried - running it for a while since its only intermittent, running has not improved
    - checked fule bowl for water, seems clear
    - checked spark, strong consistent spark on all 3

    therefor must be carbs in need of a clean??

    problem - 6 bolts underneath carbs are rusted up and don't seem to budge and cant get a socket on the
    - cant get a spanner on the other little nuts that would allow me to remove the carbs that way

    does anyone have any suggestions? like blowing compressed air down the fuel lines to try and dislodge any blockages?

    Is this machine new to you?

    Has the driveline been inspected and/or serviced in recent memory?

    Now might be a good time to remove the jet pump and drive shaft. Then remove the engine so you can work on it easily.

    Using a stubby 12mm wrench (box end or combo) can help, but it is awkward working under the carbs with the engine in the hull. Try reaching over while standing on the far side of the engine, might make it easier to get your hands in there.

    If you can't find a short enough 12mm wrench, some guys made their own by cutting down a regular length wrench.

    Xlint89 has posted some tips in this regard, somewhere on here.

    And here

    not new to me, had it for about 3 years and the drive line has been serviced with new bearings and prop,

    my dad has an immaculate slt and we have had the carbs off that and cleaned them out 2 times before and it wasent that much of a hassle, because everything is in perfect condition with no rust ect and they came of quite easey, just my ski altho has ran perfect till now is a bit more rusted in the nut and bolt department so this simple task has become a huge pain in the ass

    in your case I would pull the intake with the carbs so you can replace the rotted nuts

    A Craftsman 12mm coimbination wrench is just the right length to get in there and get the nuts loose.

    A ratcheting wrench is of great help once you initially break them loose.

    Penetrant soak, such as PB Blaster or Kroil.
