Chuck Nuytten has been doing carburetors for over 35 years. His carburetors and fuel systems have carried drivers to countless numbers of wins and championships worldwide. This success is a result of Chuck’s attention to detail and quality. All carburetors start with new Holley® cores. Each carburetor is then modified according to rule limits, type of fuel, and then set up for your motor combination. Chuck personally follows the steps of each carburetor and calibrates every one himself. This kind of personal attention guarantees that you will get the best performance.
Chuck Nuytten’s alcohol conversions have innumerable modifications to flow enough fuel through the carburetor. These modifications include larger needles and seats, larger passages, and extensive circuitry modifications for a proper fuel curve. This allows most of our alcohol circle racers to run block mount mechanical fuel pumps. This ultra simple fuel system makes more power than the complicated systems and costs considerably less.
