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.

Stock OEM
Carburetor (Suzuki and Kawi) (Kitty Cat)
-
Limited number of carburetors are still available. Arctic
Cat is still providing these carburetors, but as soon as they see a
drop in sales they may quite offering them.
- New OEM carburetor for
either Suzuki or Kawi.
- This carburetor
replaces and resolves the continued problems that everyone
experiences with the OEM Kawi engines.
- The OEM carburetor for the Kawasaki is $5 more than the Suzuki because of the modifications required for the carb to fit the Kawasaki 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.)
