Weber has long been acknowledged as the manufacturer of the best carburetors available....ANYWHERE.  Legendary marquees like Alfa Romeo, Aston Martin, Ferrari, Lamborghini and Maserati have been closely linked with the products of the equally legendary Edorado Weber S.P.A. of more than 50 years.  While various producers of racing and high performance induction systems have moved in and out of the limelight over many decades, Weber alone maintains its worldwide superiority. The foundation of Weber's supremacy is no mystery.  It's nothing more than the traditional virtues of careful design, meticulous manufacturing standards and uncompromising quality control, coupled with that unique Italian attribute of elegance in design. Do not confuse this with WeberNorthAmerica - not the same company. Weber North America brands various carburetors as "WEBER's" under a licensing agreement but they are NOT the legendary Italian designed and European built WEBER. REDLINE uses exclusively the European WEBER carburetors in their conversions. This item is the linkage kit, adapter plate, and air filter adapter - it does not include a carburetor.
