18mm Mikuni Carburetor (Kitty Cat)

• Outstanding performance and durability as the Mikuni name has earned!!!
• Excellent fuel control with easy adjustments for fine tuning.
• At almost a 10% discount, the CARB KIT comes with everything listed below plus installation instructions.
• Specifically used on Kitty Cats for racing as these carburetors are touchy and require detailed setup.  If you're not racing I strongly recommend purchasing the OEM replacement carb below.
• Note:  We only have three carb flanges left and therefore this complete kit is only available until those three are sold out. Individual 18mm carbs may be special ordered without flange and cable...call for in-stock information
• WARNING: The 18mm carburetor alone does not directly mount to the cylinder. It requires a mounting flange and therefore you'd need the entire kit unless this is just a carb replacement. Please don't order the 18mm carb alone if you don't have have a mounting flange already on your engine.

Carburetor Parts (Kitty)

• Use on Kitty Cats to increase fuel flow and tune performance. (NOTE: Mikuni Carbs Only...Not For Use With Kakaki Carb On Kawasaki Engines)
• The OEM carburetor comes with a 1.5 needle & seat (N&S), which is the device that controls the fuel flow rate entering the carburetor.  The 1.5 size is fine, as long as you don't bypass the governor.  As soon as you bypass the governor and the RPMs increase, the demand for fuel is greater and the 1.5 N&S is not large enough to meet that demand.  Therefore, we offer the 2.0 N&S as an upgrade to ensure the fuel flow is correct.

• The Pilot Jet controls the rate of air allowed to enter the carburetor and mix with the fuel.  The #35 pilot jet was used from 1977 to 1992, then the factory changed to using a #40 pilot jet. from 1993 until 1999.  Either will work fine for your Kitty Cat, and some customers split the difference with a #37.5.

• These main jets are used specifically on the Kitty Cat and controls the fuel rate allowed to move from the carb bowl into the carburetor nozzle and then onto the throat.  The leaner the engine runs to a certain point, the better engine performance.  In other words, the closer the engine is to burning down because it's too lean, the better the engine performs.  What's too lean?  That's the question for every snowmobile.  It's up to you to determine that.  A 72.5 main jet was OEM, except for 1977 where it was a 77.5 and TOO rich.  Most people change the main jet to a #70, which seem to be a very good option.  Some racers will use a 67.5 main jet, but they risk a melt-down and are very careful to take into consideration the temperatures.  The colder the temperature, the less dense the air is and the more your engine runs lean.  Please email us if you have any questions about this topic.  (OBDi does not assume any responsibility or liability for damages done by changing the OEM configurations.)
