Electrical feed back is not something most would even think of, but definitely worth checking. However in my case, I know the connections are new, clean and good. That said I will double check.
My thoughts right now is to take the Lokar carb connector idea and machine my own. I don't like the set screw to hold the cable into that connector (if that is what it is). I will then use the existing cable outer, use a thicker ss inner cable and make up a new, replaceable pedal connection, yet to be devised. I want something that is easily repairable but hope I never need to again.
