    Question 1996 Polaris SLX 780 IDLE ROUGH

    I have a 1996 Polaris SLX 780. I got it running, it has sat for a year or more not sure, it starts up every time (so far haven't had it on the water yet) but it idle's rough. It sounds like its going to die especially after I rev it up, when it revs down it really sounds rough! I have not dropped the bowls on the carbs or tried any thing else. It idled fine untill i sent water through the exauhst.

    Thanks for your advice

    What do you mean by 'sent water through the exhaust'?

    Have you downloaded the service manual, and worked through the diagnostics sections?

    Compression check?

    There are a number of common things to do to get a Fuji engined Polaris ready for the water. Have a look around the linked web pages above, and use the Search function here.

    Lots of good info to be had.

    Like he said,^^^^^^^ what do you mean water through the exhaust?

    Did you use fresh gas?

    First thing you need to do is inspect the carbs. And FYI: there's no bowls on them.

    Also replace the fuel hoses if they are original.

    Check the water/fuel seperator.

    Clean/inspect the petcock.
