They say they stock all components replacement parts, which is another plus. Heres what Mr. Hewitt wrote regarding adaptability : "Since the carburetor manufacturers could not continue to make each factory specific carburetor model, they would make a Universal to retro-fit original applications and unlike factory carburetors with fixed jetting and fixed throttle throw, the Universal models allow the full adjustment of the throttle lever to suit different hookup's; slotted base bolts to fit the small base US standard 1bbl (2 11/16") and also the larger flange (2 15/16"). The Universal carburetors also used a external adjustable high speed main jet to allow the fine tuning of the high speed circuit so you can match up the main jet orifice size to suit your particular engine, without tearing the carb apart and guessing at a correct jet size. This is a simple process based on the manifold vacuum your cylinders produce with the throttle open and the engine running at speed (2000-2500 rpm). Same principal as adjusting a idle circuit, except on the high speed side"
