Here you find alternatives to Tillotson or Diaphragm carburetor and the stock style carburetors built and tuned for your engine application. We take our decades of carburetor experience and hours of dyno time tuning and calibrating our slide carburetors to get the most from the specs of your engine and application. This is a growing segment of carburetors to address the lack of tuning experience required for Tillotson or diaphragm carburetors. Our goal is to still deliver the highest performance from each carburetor that satisfies the need for speed.
