What is a Honda carburetor?

Our Honda range of carburetors includes motorcycles, ATVs, motocross bikes and various fields. If the motorcycle carburetor is not adjusted correctly, the engine receives the wrong fuel to air ratio, which can cause performance degradation and possibly damage the engine.

Our biz125 carburetor,cbx250 carburetor and trx400 carburetor trx500 carbureto are all very high quality carburetors. When not enough fuel passes through the carburetor, the engine becomes "runny," which can cause serious engine damage. When too much fuel is allowed through the motorcycle carburetor, the engine is "overoiled", which results in a significant deterioration in engine performance. Carburetors, while still used in many household items with internal combustion engines, have been replaced by fuel injection in automobiles.


How does a Honda carburetor work?

1.      The gas flows into the buoy through the fuel pipe. The bowl has a float connected to a needle valve: once the bowl is filled, the float closes the valve and stops the fuel flow.

2.      The gas in the bowl flows into the primer nozzle, which keeps the fuel flow minimum, and the main nozzle, which adds fuel as the air flow increases. They sit above the Venturi tube, a restricted airway that increases the speed of air passing through the intake to help fuel mix with the air.

3.      The throttle is just outside the venturi tube and controls the flow of fuel and air to the engine. The choke valve, located in front of the ejector and venturi tube, limits airflow to increase the fuel to air ratio. This richer mixture makes it easier for the engine to run on cold fuels that do not want to be atomized.

4.      If all is well, the valve keeps enough fuel in the bowl to feed the jet, delivering the right mixture of air and fuel to the engine for efficient operation.


Symptoms of carburetor problems

1.      Most problems stem from gasoline varnish and limiting injection or preventing throttle or idle valve movement. To prevent this, always use fresh, stable fuel and empty the tank and carburetor when storing equipment for the season.

2.      If the engine only wants to run with the choke closed, the main nozzle may be blocked. Once the choke is open, the fuel mixture becomes too thin for the engine to run. On some motors, the automatic choke will engage when engine speed drops and then disengage when the engine accelerates again, causing it to surge at idle.

3.      If the engine does not want to idle regardless of throttle position, the ignition injector may be blocked.
