I have a 1991 Fatboy, with Arlen Ness big Sucker I kit on CV carb and Thunderheader exhaust. Carb Gurus, what would be a good jet combo?
I do`nt know about an "aftermarket" fuel spitter for H.D.Thank God for fuel injection.
I hated working on carbs. All carbs. They truly suck.
Holley made generic throttle body fuel injection for cars, the technology should be pretty mature, since it's been available for 20 years, does anybody make an aftermarket throttle body fuel spitter for HD?
I don't know how you adjusted the float but if it's leaking from the overflow tube rather than the bowl o-ring my WAG is that the needle valve is not closing between 0.413-0.453 on the float height with the carb @ a 15-20* tilt. Put a piece of tubing on the fuel inlet & blow thru it to tell exactly when the needle valve closes.
If that's the problem you need to check jetting again because a flooding carb creates a rich fuel/air mixture.
Hope this helps.
