    way way to much!

    you can do them your self or find a diffrent place to bring them..

    i got mine done from a good shop for 300 thats with them figuring out the problem and reinstalling... not that installing carbs is hard.. but still didnt think it was a bad price to have a experinced hand redo thecarbs

    but you need too look into the fuel lines as well.. and replace the fuel pump with a tripple out lit fuel pump.. click the link in my sig and read read read

    Yeah you can rebuild carbs for about $ 150.00, be sure to replace needle and seats and check pop off pressure before reinstalling. I had never done mikuni carbs before either, but they werent that difficult. Be sure to go through entire fuel sys.
    good luck Brian

    It really doesnt matter much about hours,or that it was stored under a cover. The problem is the fuel they left in it, & the rubber fuel lines rotting away from tank to motor. Thats why people emphasize the fuel sys.be inspected from fuel pickups to the fuel rail.& the 3 outlet mikuni pump.

    Easy Peasy. The 750's were a little goofy the way Polaris routed the fuel but a triple outlet fuel pump upgrade kit from John Zigler solves it all.

    Here's the general rundown for the fuel system:
    A nipple from the crank case provides vaccuum to the pulse diaphragm fuel pump.

    The pump will have a nipple for pulse, one inlet for fuel, and the upgrade kit (an absolute must) will will have 3 outlet nipples to feed each carb.

    The shutoff switch has 3 hose connections: one inlet from the tank, one inlet from the reserve, and one outlet to the fuel pump.

    The tank will have 4 hose connections on the top: one outlet, one for the reserve (this is just a supply tube that sets deeper in the tank), one for the return, and one that goes to a check valve vent.

    The carbs each have an inlet nipple and then return nipples that are interconnected with short pieces of tubing. The rear (PTO) carb has the final outlet nipple that is the return line to the tank. Inside this tube will be a restrictor (about 0.85mm diameter). With the condition of this ski, the restrictor is probably there. This piece is absolutely necessary to maintain sufficient backpressure in the fuel system.
