Carburetor Parts
About Carburetor Parts
Most carburetor problems on an ATV or older UTV come from small parts: a hardened gasket, a stuck float needle, a clogged jet or a worn diaphragm. This category holds the repair kits and tuning parts that deal with them, so a carburetor can be rebuilt rather than replaced.
Repair kits are listed by make and model, for example Polaris, Kawasaki, Honda, Suzuki, Yamaha and Can-Am, and they are matched to a particular carburetor, so match the kit to your machine and year. Contents vary, so read the listing. Jet kits, such as the Stage 1 kit listed here, are for tuning. They are meant for machines with a modified intake or exhaust, or a change in altitude, and they come with instructions. Before you take a carburetor apart, photograph it and note where each jet and screw goes. Clean passages with carburetor cleaner and compressed air rather than wire, which can enlarge a jet.
Brands in this category include Athena, Mikuni, WSM, Parts Unlimited and Dynojet. Related groups are Carburetors, Fuel Filters and Fuel Valves & Petcocks, all part of Air Intake & Fuel Delivery. Pick your machine in the Ride Finder at the top of the page.
FAQs on carburetor parts and repair kits
When does an ATV carburetor need a rebuild?
Common signs are hard starting, a rough or surging idle, hesitation under throttle, fuel leaking from the overflow, and poor running after the machine has sat with old fuel. Check the fuel, filter and air filter first, then clean or rebuild the carburetor.
What comes in a carburetor repair kit?
Kits usually contain the gaskets, seals and small wear parts needed to rebuild a carburetor, but contents differ between kits. Read the listing and check that it is made for your carburetor, because kits listed for one make or year may not suit another.
What is a jet kit for?
A jet kit supplies jets, and sometimes other parts, so that fuel delivery can be adjusted when the intake, exhaust or altitude changes. It comes with instructions. Fit the parts the maker advises, and check the engine's behavior and spark plug color afterward.
How should I clean carburetor jets?
Use carburetor cleaner and compressed air, and let the jets soak if needed. Do not push wire through a jet, because it can enlarge the hole and change the mixture. Replace a jet that is damaged rather than trying to repair it.
