    Ahh, the infamous accelerator pump issue arises again. LoL
    I have the same problem after rebuilding all three carbs and did a lot of searching on line to find this is a common problem with the older Polaris models.
    The bigger problem is, getting a new one or even the parts as it's no longer available on the microfiche (carburetor part #15)
    http://partsfinder.onlinemicrofiche....pe=13&A=60&B=8
    I already checked Ebay and nada uno.
    So I'm going to post you a few links here to read for yourself.

    And going to contact Randy at:
    http://www.babbittsonline.com/pages/...d/default.aspx to see if he has the parts or if one of these will work:

    I'll keep you informed if I have some success on this matter. It's so simple yet takes time to get.

    BTW, I just added a few new goodies to my SLX and it shreds like a raging bull! Almost threw me off a couple times in turns. Have major thrust and torque coming from it since the mods. Just crazy .)

    An inoperative accelerator pump will not limit the engines maximum RPM. It will cause a hesitation or bad stumble on acceleration only. With a bad accelerator pump, you can accelerate slowly & easily get past the hesitation to get full operation. As the name says, an accelerator pump only works when you accelerate. It does nothing to maintain RPM at any throttle position.

    I would start by checking the compression & replacing the spark plugs. If these are OK, you could have damaged reeds or a bad coil.

    Question elevation after 2000 ft, jetting, sea level

    Chester, can you advise on this article?

    * red text summs things up quicker for those into speed reading LoL

    ----

    I posted before about this problem at idling, yet running fine at mid rpm range and up, and not sure if it is or isn't the accelerator pump now due to the following weird discovery.

    Took the two skis out yesterday (XP and the SLX)
    Was about noon when we launched, and I already knew of the problem idling the slx, but had hopes and wishes to get a bit of riding on it yesterday, no matter what.

    The temperature was hot and full sunny day. She bogged at low rpm but if I used the choke, it seems to have stopped it from cutting out/dying completely.
    So messed around with this finding a few times until I switched over to the xp to ride.

    SO...the end of the day comes, it's now about 7p.m., the sun is now behind the mountain and the air is cooling off quickly.
    Back the trailer to the ramp and load the xp first.
    Then fire up the slx and low and behold, everything is running awesome.????

    Just to be sure it isn't a fluke, I take a few test rides before taking it off the water and it ran just perfect. Idle was fine, starts and stopped fine. Full acceleration from idle up was fine also, and just like there wasn't an issue at all.
    So this baffles me.
    And now that I think of it, I got this ski in the spring, ran fine. Warm weather came, ran bad. Yesterday's cooling evening ran great.
    Is this a carb tunning issue? Jets? Settings?
    But before answering, here is something that I have to also consider and has to do with the history/location of the original owner of this machine:

    Tracing the roots:
    Original owner got the ski new in 1999 and lived in Alberta Canada.
    Next owner had it shortly and lived in the outskirts of Vancouver Canada.
    Owner after that also had it briefly, then I got it.
    The other two people who had the ski probably had issues with it as well and decided to sell it when things went wrong for them. This being the idle issue I would assume. After all, since 1999 the hrs meter read only 140 hrs when I got it (=15.55 hrs/yr. avg) so it was ridden very little and everything looked new above and below the seat.

    * My latest finding:

    Alberta Canada is 2200 feet above sea level. Vancouver is at sea level.
    Hopefully this means something which I need to learn more about.

    It appears like you have a jetting/tuning problem. Are there any modifications done to the engine? If the engine is all stock, check to see if the proper jets are in there and the mixture screws are set to manufacturers specs.

    This problem happened before I did the reeds, impeller, rebuild of the carbs and such. Nothing internal was done.
    I'll have to pull them out again to see what they are. Will have to wait a couple weeks or so before i can get around to it.

    Q: Could it be as simple as the mixture screw settings before I tear it down?

    If it came from a higher location it would have larger jets in the carb. This would not cause this problem. Have you changed your fuel filter? If so you may have some dirt in the carb. I would add some carb cleaner to the gas and change the fuel filter. If this does not work the coil could be breaking down in hot weather. Don't run your ski with this leaned out condition as it will burn the pistons very fast. Hope this helps!
