Carburetor Rebuild Kits

Is the engine stumbling at idle, is the carburetor flooding, or has it been sitting all winter? A rebuild kit brings together the wear parts you typically need to get the carburetor working properly again – for you who want to take it apart and restore it yourself.

Complete kits and individual parts

The category includes both complete rebuild kits and individual parts. The complete kits from e.g. QuadBoss are listed for specific models, e.g. Honda TRX350FE/FM/TE/TM, Kawasaki KLF220 Bayou or Yamaha YFM660R Raptor. If only one function needs fixing, you will find parts such as needle and seat, float, power valve and idle mixture screw kits. A calibration kit is typically used to fine-tune the mixture; the kit from Edelbrock is listed for 1905 / 1906.

How to choose the right kit

• Model and year: complete kits are listed for specific years, e.g. 00-02 Arctic Cat 500 4x4. Compare with your vehicle.
• Carburetor type: individual parts must fit your exact carburetor, so check the product text, e.g. the note 1975 & Later on the float.
• The symptom: flooding typically points to the needle and seat or the float, while a rough idle can be caused by the idle mixture. Lack of power under load can, among other things, be related to the power valve.
• Scope of the project: if the mixture needs changing, take a look at carburetor jets, and if the carburetor is worn out, you will find new ones under carburetors.

Installation and maintenance

Take the carburetor apart on a clean surface, clean passages and jets thoroughly, and replace gaskets while it is open anyway. The float height is typically set to the manufacturer's specification, and the idle mixture is adjusted with the engine warm. Fuel left for a long time in the float bowl can leave deposits, so drain it before long-term storage.

Frequently asked questions

Should I choose a complete rebuild kit or individual parts?

If the carburetor has been sitting for a long time, or there are several faults at once, a complete kit typically makes sense. If the fault is limited, e.g. flooding, replacing the needle and seat or the float may be enough.

Why does the carburetor flood after a rebuild?

This is typically caused by an incorrectly set float height, dirt between the needle and seat, or a float that does not move freely. Check the float's function and height before refitting the carburetor.

Does the carburetor need adjusting once the new parts are installed?

Yes, typically. Idle and idle mixture are adjusted with the engine warm, and if you have changed jets or the power valve, it may be necessary to check the mixture at different revs and loads.
