Alpha Plus Velocity Carburetor Insert 7.0mm
E22-BU02100
E22-BU02100 Alpha Plus Velocity Carburetor Insert 7.0mm
Alpha Plus Velocity Carburetor Insert 7.0mm
This is a replacement Alpha Plus 7.0mm Velocity Carburetor Insert, as used with ALL Alpha .21 Engines.
The carburetor venturi is used to adjust the airflow that is allowed into the engine.
By changing the size of the venturi, you can fine tune the power delivery and run time of the engine.
A larger venturi will increase top end power, while at the same time reducing run time.
A smaller venturi will improve bottom end throttle response, and improve run time.
