I'm having a heck of a time trying to track down the specific part(s) needed to remedy a stuck throttle cable pulley on my carb. Between not finding the technical name used by the industry and not knowing whether or not it's replaceable, I've been stuck for a couple days. I call it the throttle cable pulley but I don't know if that's the correct term when looking for replacement parts. Or, maybe it's not replaceable on its own and a whole new carb is needed? Personally I think it's nothing more than the spring. Attached is a photo of exactly what I'm referencing. Thanks in advance for your help.
