EMPI 34 PICT-3 Stock Replacement CarburetorEMPI stock carburetors are excellent quality replacements for a stock carburetor that is malfunctioning. Sometimes the choice of which carburetor to use can be confusing, particularly when replacing a carburetor that may have previously been replaced by another non stock one. The choice of which EMPI carb to use is simple: We recommend using the 30PICT 1 for single port applications, and the 34PICT 3 for dual ports.
