What\'s the red thing by carb?(for wiring) Hi, still in wiring hell. There's a small (1" x1") red rubber/plastic coated piece with places for 2 wires at the bottom, that is attached to a metal bar. The metal bar screws into a plate back of the carb and the throttle cable goes thru a hole in the bar. This little red thing is right next to the hole where the throttle cable comes through this metal bar. There is a small metal arm at the top of this red thing that moves back and forth. Anybody know what it is, and what wires go to it?
