How does a carburetor work?
A carburetor’s job is to supply an internal combustion engine with air/fuel mixture
A carburetor works by mixing air and fuel to allow for internal combustion.
Pros of using carburetors
- Carburetors aren’t costly when compared to that of a fuel injector
- The operating mechanism of carburetors is straightforward.
- Carburetors aren’t integrated into engines, which means they can be replaced or serviced without affecting the engine.
- Air and fuel mixture is perfectly done with the component.
- It has more power and precision of the air/fuel mixture.
Functions of carburetors
- The primary function of a carburetor is to allow a suitable amount of air and fuel needed to produce power.
- It regulates the air-fuel ratio and also mixes the fuels.
- Controls the engine speed.
- Helps the fuel to burn smoothly and properly without any problem.
NICHE Careburetors
ATV Carburetors:
Most ATV carburetors use a simple design. They have a vertical air pipe that’s strategically located above the engine cylinders. The vertical air pipe is then joined to a horizontal fuel pipe (at the narrowest part of the venturi) which allows for the passage of air into the engine’s inlet manifold. The inlet manifold, also called the intake manifold, is part of the engine that supplies the air/fuel mixture to the cylinders
Motorcycle Carburetors:
Regulate the flow of air through their Main bore (Venturi), this flowing air draws in fuel and the mixture enters the engine via the intake valve.Turning the throttle on a motorcycle handlebar does not directly control how much fuel enters the engine. The throttle controls how much air is allowed to flow through the carburetor, and the flow of air is what controls how much fuel is also fed into the engine

Delivered on time and worked perfectly right out of the box. Minor throttle cable adjustment and the 4 wheeler was ready to ride. I’ve purchased several Niche products from this seller and have not been disappointed.

This carburetor works just fine, I did find out that you will need to order the original OEM Polaris main jet and pilot jet. This made a big difference. Especially the pilot jet, it is not fluted and will not idle correctly

Super fast delivery, got it day after I ordered it! Right out of the box with no adjustments it corrected my low speed hesitation and smoothed out running at all speeds, at idle now it's smooth as silk!

Carb worked great after adjustment to fuel bowl float. That's just the kinda thing you'll tinker with because not all machines are the same. Thanks!I have a 2005 Polaris Trailboss 330 btw.

Leaked gas constantly from overflow, would not take any adjustment for air fuel mixture. Idled great but died once throttle was given. Replaced from another seller and with the 2ndbnew carb, the quad runs great. Maybe just a bad manufacturing run? Who knows. I would not recommend

Would not run right. Polaris even tried to adjust but couldn’t. Vacuum port had to be JB welded for it to stay in place
