V Stack with integrated choke

These V stacks have been designed with the racing in mind and can be used with a "green weenie" or K&N type filter if needed. Having an integrated choke within the v stack will allow for the removal of the choke shaft and butterfly from the carburetor which will increase airflow through the carburetor. 

These stacks are 3D printed from PLA, and have a choke mechanism which is made from mild steel. External diameter is 1.90 inches. Height is 1.115. Will fit Stihl saws that use a HD or WJ series carburetor.

Not recommended for work saws, as fines might pass through the v stack where the choke is located.

Overtightening the carb nuts will result in an inoperable choke.

Because this is a custom, purpose specific component, we will allow preorders.

Orders will be fulfilled in 2 weeks or less.
