I tried looking around some, did not find anything just like this. quick background. 1989 FLSTC. been in storage for a few years. took out, cleaned up, changed oil, drained tanks, fresh fuel, new battery, took off carb, rebuilt and cleaned, wasn't too dirty. turned over and cranked right up. idles ok, but doesn't take fuel well. If you try to rev, it tries to die.. drives fine, except if you throttle up rapidly. like say passing a car. there is a slight hesitation then takes off. Any ides?
