In many situations drag cars require additional pump shot to cover a lean stumble condition from a tight converter, large camshaft, excessive intake plenum volume, or low vacuum conditions. The best fix is to install a 50cc pump assembly. Our complete kit includes pump housing and screws, spring, pump cam and screw, diaphragm, and complete pump arm assembly.
