The HW Tillotson Avenger Series is the first of Tillotson's modern carburetor models that change the appearance and performance from the traditional chainsaw power equipment diaphragm carburetor into a high-performance racing product.

The newest Tillotson Carburetors utilize a two-piece throttle shaft that separates the throttle lever from the throttle shaft giving the Tillotson carburetor even more modular options.
