  • 1999 900 Stx carb questions

    Installed the standard kit 35-211, no good instructions online, yet found the following

    there is a small filter on the brass check valve, it was clogged with gunk on the end of the check valve, I am assuming this is why the the jet ski bogged down and shut off when hitting the throttle last time out.

    The fuel rail also had gunk, cleared it out with carb cleaner,

    there was nothing in the area where the needles spring was at.
    I did not pull up the plate just under the float/spins device, is that where the high speed jet is?
    i assume check valve screw should be fully tightened. Any other trouble areas I should check while the carbs are off the engine? I as did notice the flame arrestors tubes just fall apart. Have to buy new ones, poor quality on original,
Working...
