    1986 Polaris SL780

    I just put a new engine in rebuilt the carbs it fired up and ran great for about 20 seconds now it won't clean out smokes bad plugs are covered with fuel the exhaust is covered with oil I plugged of the oil injection like they recommend and mixed the start up oil like it said spark is nice and blue it will only run 7 mph on speedometer holding it wide open any ideas im grasping at straws now

    Welcome!!! I am guessing you have a 96 SL780, as they were not made in 86. Check the last two digits of your HIN plate to verify....

    Who recommended removing the oil injection?
    Whose instructions did you use for mixing the start up oil?
    What RPMs are you reaching in the water?
