Larry Tipton has spent most of his life in carburetor design and development. He began with Carter in October 1966 in St Louis as a designer of carburetor components and later was appointed to the advanced design group for new carburetion. Today he is the inspiration behind the new 625 Street Demon. 1) What was the inspiration behind the Street Demon? “Since its beginning Demon Carburetion has specialized in racing carburetors, usually for drag racing and for oval track competition and for street-strip and muscle cars. Later the Demon SixShooter and the Demon 98 carburetors and their attendant intake manifold systems were...
