A precisely tuned, quality-built carburetors should be able to handle the rigors of daily driving while delivering consistent, reliable street performance from day to day. Several characteristics make our carburetors outstanding street performers. The first one is that they use metering rods to transition between circuits. They are unaffected by engine backfires, which means that there are no power valves to blow out, and the rods can be changed in seconds without carburetor removal or fuel draining. Secondly, they have the unique ability to "hold a tune", so once they're tuned, they stay tuned. What this means to you is that compared to other carburetors, the performance remains consistent and the calibration stays unchanged. The lightweight all-aluminum body features a two-piece body that resists warping and is compatible with gasohol and blended fuels. The simple tub-type bowls and rear-pivot floats all contribute to a carburetor that's reliable, user-friendly and is easily tuneable for miles and miles of trouble-free operation.
