In the world of performance camshaft selection is often a critical choice in how your engine performs. Small engine racing, unlike the automotive world, there are limited choices in cam builders and cam catalogs. Around the time we had the concept of what would become the Tillotson 225RS we started piecing together what components we needed to achieve a strong power band for a relatively low rpm engine ideally for mini bike engines. 

EC Tech Review: The new Tillotson Racing Blocks designed by EC Carburetors

We have been the primary Tillotson importer and distributor for kart racing for over 35 years. Not only are we master blueprinters that can get the most from a Tillotson carburetor that dominate the limited and open races across the country, but we have also designed many different base models for Tillotson in that time. Tillotson trusts our knowledge and expertise. That's why they came to us to help them develop their engine programs.
