I know of a Tillotson brand carb that was on a stock sportster.
42 pilot 150 main for stock Keihin butterfly carb.
Depends on the model.
why can I not stop the leaking of gas from the carburater on a 1994 harley
Full Length Harley RoadKing Injected ( fuel injection instead of carb)
Running stock exhaust, a CV carb, and no internal modifications you're looking at about 54 hp.
Check the plug gap / check timing , check jets in carb
The s&s super e is by far the best.
Change out the intake Gaskets and Carb. Gasket. You have a vacuum leak.
The 1983 FXSB came stock with a Keihin B28E 38mm butterfly-type carburetor. First use of the Keihin CV carb was in '89 for Sportsters and '90 for all big-twins.
Unfortunately not: The 07 Sporties are EFI (fuel injected), thus requiring o2 sensors (and sensor bungholes) in the exhaust. 06 bikes, on the other hand are use a cv carb that does not need the sensors or bungs.
Harley stopped using carburetors on all their bikes after 2006; now they're all fuel injected. But the last type of carb used was the Keihin CV (constant velocity) which was based on the British Amal slide carb from the Forties. Before that they used a Keihin butterfly carb, and before that a Bendix-Zenith, and before that a Tillotson, and before that a Linkert, and before that a Schebler and the very first Harley carbs were made by the founders themselves, with the help of Ole Evinrude of outboard motor fame.
William S. Harley and Arthur Davidson were boyhood Friends who were working together for the same firm in 1901; Harley was a draftsman and Davidson a pattern maker. They started working together on an engine design. Exactly the same engine design that is used to this day. Ole Evinrude (of now legendary Evinrude outboard motors) helped get the carb design right. In 1903 Davidson's two older brothers, Walter and William A., left their railroad jobs to join in to get the design right. Walter was a mechanic, W.A. was a tool maker. The first factory was a 10'x15' shed built by the Davidson's father in the family's back yard. William Harley enrolled in engineering at the University of Wisconsin. The rest, as they say, is history.
