Hey guys, I pulled the trigger on my post to quick. I did have one other question. This system has some kind of a diaphram "pot" on the side of the carb. there is a wire running to a knife post & there appears to be a Vacuum line going to the pot from the intake side of the carb. Any chance this is some kind of electronically controlled choke? How would it function? I didn't have time to run the wire before I left this AM, but there is some type of switch that energizes the regulator that goes hot when the key is on. The wire leaves the neg coil to that switch and there are several wires staked together on the switch terminal. I don't know where they go. Maybe to the carb Diaphram? If the choke is stuck closed adding carb cleaner might flood it? not enough air? I'm grasping at straws. Any ideas what the diaphram could be other than a choke control? Throttle is straight mechanical. Might pull carb first? Thanks again. Rich
