1) What size pilot jet is in there?
2) How many turns out on the Idle Mixture Screw
3) What needle are you using?
4) Does this carb have any Dynojet parts?

Carefully read over this... Then record all the parts in the carb - Take pictures if you can...

Beg/borrow/buy a timing light and clear plug for the timing hole - I would definitely check the timing...

Here's the Sportsterpedia section on timing:

Post the information and pictures here...
