Throttle return issue?

[Guy Ramsey]

I've been having a problem with my throttle return. It tends to hang up for a second before returning to the idle position. I looked that the microfiche on bikebandit.com and couldn't figure out which spring was the return spring on the carbs. Anyone replace this before and have a part number? I suppose it's possible I'm looking in the wrong place to solve the problem too... Has anyone had a sticky throttle and what they did to fix it?
