I want to but a carb for my 79 Regency, The part that moves up and down when you hit the throttle wont move anymore. Im interested in buying the same one or one that you think that might work. Im pretty sure that this carb is differnt from both the 25 and 30 mph models that i always read about. It was a long black box like airbox, not a round top of a spray paint can looking thing. Let me know if you can help me out i gotta get my baby on the road. Im in the Bay area.
