    leaking carbs

    i have a polaris sl 750 , cleaned carbs , did a pop off test everything checked out good . ski ran great right off , did have to richen up a bit , so i was thinking awsome got two running skis time for some family fun ...NOT ...i was goin over ski checking gas connection and what not and felt some gas coming out of hole of diaphram plate on carb...not alot but is leaking ...is this at all normal or do i need to get a rebuild kit since i can find the diaphrams seperatly, or if anyone knows where i can get them seperately would be great. common sense tells me its not normal, but i have an extra set of carbs(never touched) and can see where gas has leaked from all three of those too

    Only air should be coming in and out of that hole. If you have gas coming out of it, you have a problem. Either the diaphragm has a crack in it, or the plate isn't seated on there right. Don't want to insult your intelligence, but make sure that you have the tab on the plate aligned correctly (I can say that because I've been guilty of that ).

    Now get this...When I was rebuilding my carbs off a 780 earlier this year, I kept the diaphrams thinking, "I'd hate to throw these away they are perfectly good." So I didn't, and threw them in a ziploc. The oil nipple in the 780's keeps the carbs nice and lubed.

    Anyway...not sure if they'll help, but send me an address and I'll put them in the mail tomorrow. Nothing to lose.

    Those may have pin holes you cant see. I would buy new ones for all 3 carbs. These skis go lean and burn pistons not to mention the fire hazard. They are 15.00/piece. Remember, you cant watch the carbs while riding. Gas leaking is very dangerous.
    you can buy them on ebay or a powersports store. Full rebuild kits are 45/piece. Well worth the price and piece of mind.

    John Zigler is an excellent source for Polaris carb rebuild kits and OEM carb parts.
