At a glance
What can fail
The fuel tank valve assembly can become plugged, causing the carburetor to overflow fuel or restricting fuel flow. On certain M2 Cyclone models, a component may block airflow into the carburetor's float bowl, causing similar overflow or fuel flow problems.
What the fix does
The fuel tank vent valve assembly will be replaced. M2 Cyclone models will have the float bowl assembly inspected and corrected if needed for proper venting.
