Welcome to the HDForum Dad!
yes as Badinflunce ask whats going on with your engine?
Also tell us as much as you can about your bike, engine modifications, what kind of pipes, cam, cubic inches, ect.
heres another page with tuning instructions
did you know that not having the overflow tube attached to the float bowl can cause the engine to run poorly at higher speeds? The reason I am saying this I just read this in the instructions for my S&S "E" carburetor.
