EC Carburetors have been the leader in small engine carburation for over 40 years in karting. But to make these carburetors work, you need an intake adaptor to replace the stock carburetors. You will find many manifolds to adapt Tillotson carburetor and other carburetors to engines that are not common in sanctioned racing. Our universal intakes allow innovation and development for the few using rare or exotic small engines.
