What causes gas to leak from a carburetor?
A stuck carburetor float is by far the most common reason why a carburetor can leak gas. While it mostly causes a delayed engine start or an engine stall, it can also lead to fuel leaks. Thoroughly cleaning the carburetor float, float valve needle and float pin should allow the float to move freely again.
What is a float needle valve?
The float valve is a fantastically simple mechanism to regulate fuel needs for the carburetor. When the needle is forced all the way in it blocks the orifice and stops fuel from flowing into the float bowl. Fuel can flow into the float bowl when the needle is retracted from the orifice.
