Heres the story on this old girl.
I rescued it from someone who was dirt biking/offroading it
When I initially bought the bike, it started and ran great, but would run out of fuel at about 75/85% load, limiting the bike to back road trips.
Carb is cleaned and reassembled by an experienced antique Harley shop with new secondary jet, new NOS float, new fuel filter, as well as having the throttle linkage cleaned and relubricated up inside the right handle.
After all this good treatment, the bike starts, but screams to high rpm immediately. You have to turn the igniton off to stop it. Lots of rich smoke obviously.
Hopefully some of you have experienced this kind of carburetion issue and can point me in the right direction.
probably going to take the right handle control apart and see if i can spot anything obviously bound or stopped up

You might try taking the cable out of the handle bar and see if it works laying alongside the tank. then start the bike and see if the throttle works pulling it with your fingers. It could be the slide in the bar , the adjuster.in the cable , or the way the cable is routed thru the frame. Could be the throttle valve sticking. When putting the cable back on did you set the throttle play at the grip.?Take the cable out of the bar and see if you can operate the throttle valve by pulling the cable with your fingers..If you can then check the cable routing then go to the throttle connector at the grip. Then make the throttle play adjustment.
