🔌 Function

The float rises and falls with the fuel level in the carburettor bowl and moves the inlet needle to control fuel entry. Correct float height is essential for stable mixture and reliable operation.

Common signs of failure:

• Fuel flooding or overflow from the carburettor

• Rich running, smoke or spark-plug fouling

• Fuel starvation, lean surge or loss of power

• Hard starting or stalling as bowl level changes

• Float absorbs fuel, sticks, cracks or no longer closes the needle correctly
