The float inside of your carburetor is a delicate component and can be damaged easily. Common causes of damaged floats are:
- Attempting to start your engine with a sealed carb hat in place. The vacuum created by the engine will cause the float to implode and/or distort.
- During the process of changing valve springs, the airing of the cylinders, with a sealed carb hat in place—the air can crush the float if air leaks past the valve.
- Filling the float bowls with a squeeze bottle. NOTE: If you fill the bowls in this manner, do not seal the squeeze bottle to the vent tube.
- Puff back or backfire through the carb. Commonly from late timing or a lean condition, the engine will 'sneeze' out the carburetor. If float levels have changed after a 'sneeze,' you should remove the bowls and inspect the floats.
