How do I know if my carburetor float is stuck?
One of the signs that the carburetor float is sticking is when the engine will not idle. The float is not letting enough fuel into the reservoir, allowing for a constant idle of the engine. The carburetor float is stuck in the closed position, and only a small amount of fuel is seeping into the reservoir.
What is the float bowl on a carburetor?
To ensure a ready mixture, the carburetor has a “float chamber” (or “bowl”) that contains a quantity of fuel at near-atmospheric pressure, ready for use. As fuel is used up, the float drops, opening the inlet valve and admitting fuel. As the fuel level rises, the float rises and closes the inlet valve.
How do you free up a stuck carburetor?
Open the hood and locate the carburetor body. Tap the top of the carburetor gently but firmly with a small hammer or screwdriver handle. Tap the bowl of the carburetor firmly. This may loosen a stuck float valve, allowing the float to work properly until you can fix the problem permanently.

Where is the float bowl in a carburetor?
Mounted on the side of the carburetor is the float-feed chamber, or “bowl,” which is essentially a miniature fuel tank fed by the main fuel tank. Because the carburetor can’t use fuel under pressure, whether delivered by a fuel pump or gravity, the float chamber is kept at atmospheric pressure.
Why is my carb sputtering?
There are many reasons why an ATV sputters. The most common reason has to do with a carburetor problem like a tuning issue, vacuum leak, or gas leak. Other sputtering issues can be caused by an ignition issue. For the combustion chamber to work on an ATV, it needs air, gas, and a spark.
