Mikuni round valve (slide) carburetors are a common form of fuel delivery used in the popular brands of two-cycle snowmachines. They use a system of jets, needles, and air control, which overlap in function, to provide a smooth delivery of fuel at all levels of engine function. These carburetors are quite simple and readily learned and can be easily maintained and repaired.

*Gasoline is highly volatile and flammable. Carefully drain and safely dispose of any fuel contained in the carburetors. Avoid working where sparks or open flame exist.

*Compressed air and aerosols may be helpful in cleaning crevices and small openings and holes. There is often a tendency for matter to rebound when compressed gases are directed in such a way. Make sure to protect your eyes!

*Disclaimer: It should be understood that the example used in this pictorial is a salvaged carburetor. This carb was not removed from a running machine - nor would a machine likely have run with it installed. It does show some of the issues one might encounter, albeit to a greater degree than one would expect to find normally. This carburetor actually shows very little wear in spite of the crud both inside and out. It will easily function perfectly again.

Mikuni round valve (slide) carburetors are a common form of fuel delivery used in the popular brands of two-cycle snowmachines. They use a system of jets, needles, and air control, which overlap in function, to provide a smooth delivery of fuel at all levels of engine function. These carburetors are quite simple and readily learned and can be easily maintained and repaired.

and in regard to the equipment...

• Mikuni Carburetors are constructed mainly of relatively soft, non-ferrous metals including zinc, aluminum, and brass. They are very functional and adequate for their intended purposes. However, one must use care, especially in working with the soft brass jets, to avoid stripping or breaking threaded parts.
