yep, what Robert said, they don't "spring" back. They all had a "dead man" throttle, same as the big twins, it would stay where you put it until you turned it back. The spring inside the carburetor is only intentended to push the slide back down when you twist the throttle grip to the closed position, it will not twist the grip for you.

I just put my throttle together. On my project 55st. New
cables and newly rebuilt carb. I greases all the moving parts
at the handlebars before putting it back together. The
throttle sticks. It won't spring back to no gas when I let
go. Any suggestions?
