How to Clean a Mikuni Ski Doo Blizzard 5500

Ski-Doo is a brand name of personal motorized sleds, or snowmobiles, made by Bombardier Recreational Products (BRP). The Blizzard line of Ski-Doo --- produced since 1979 --- was discontinued in August 2011. Earlier models such as the Blizzard 5500 are equipped with Mikuni carburetors. These carburetors require basic cleansing techniques in order to keep your Ski Doo Blizzard 5500 in optimal operation.

Instructions

    • 1

      Put on rubber gloves to protect your skin from any chemicals present in the Mikuni unit. Set the bowl on a nonslip surface.

    • 2

      Apply penetrating oil to the carburetor body to help loosen parts on the unit that have stiffened over time. Pay particular attention to the screws that hold the unit together. Allow the oil to saturate the carburetor body for about one hour before resuming work.

    • 3

      Unscrew the four screws that hold the carburetor's fuel bowl onto the unit body. Tap it gently with your mallet if it resists coming free. Remove the fuel bowl and set it aside.

    • 4

      Locate the carburetor jet --- a cylindrical bolt in the center of the Mikuni body. Remove it with the wrench and set it aside.

    • 5

      Wipe any excess dirt or crud off the Mikuni body. Spray carburetor cleaner in every orifice of the body until it flows freely out of the unit and into your bowl. Spray carburetor cleaner on the parts that have been removed from the main unit body as well.

    • 6

      Spray the Mikuni carburetor and all of its pieces with the air gun until it is dry.

    • 7

      Reassemble the Mikuni carburetor. It is now ready for use with your Ski-Doo.
