44 IDF Weber Style Carburettor (4 Progression Holes) with Chrome Ram Tubes

This 44 IDF Weber Style Carburettor is supplied with 4 progression holes per barrel. Additional progression holes smooth out the flat spots in the progression phase between idle and the main circuit, eliminating the lag experienced between 2,000rpm to 3,000rpm when compared to the standard 3 progression hole carburettors.

Calibrated components are interchangeable; venturi, auxiliary venturi, emulsion tubes, main jets, air correctors, idle jets, pump jets, pump spill jet & needle valves. This means creating and maintaining your perfect tuning combination is easier than ever.
