Description

302VS EC Velocity Stack – Tillotson Vintage 2-Cycle Carburetors


The 302VS EC Velocity Stack is engineered to enhance airflow and improve throttle response on vintage Tillotson 2-cycle carburetors. Featuring a precision-machined, radiused bellmouth, this stack increases air velocity and fuel signal for better overall performance.


Originally designed to complement Tillotson’s innovative venturi systems, the 302VS is ideal for racers and restorers looking to get the most out of their classic 2-cycle setups. Unlike basic filter adapters, velocity stacks offer superior airflow dynamics where rules allow.


Each velocity stack is CNC-machined from 6061-T6 billet aluminum for durability, fitment precision, and a professional finish. All necessary hardware is included for easy installation.

Always check your rulebook for legality before use.
