Electric issue?
Carb icing can be interesting. There was a young female around here who had a Chev pickup 6 whanger, and someone had put a ?Clifford?, big carb, and header. I ended up adding a heated water plate under the carb, and found her a smog air filter and makeshift made a stove on the header for "snorkle heat." It helped. The damn thing was nearly undriveable on cool, humid days, and it doesn't even have to be that cool............mostly just "springtime humid."
I also vaguely remember a Veedub or Corvair dune buggy when I was at NAS miramar.......had a tube intake up high above the engine, with a 2bbl. That thing was building ice on the bottom of the manifold on a HOT San Diego summer day!!
All "street" OEM engines have some form of carb heating, and Ford used to use coolant heated plates under the carb. This actually helps stabilize the temp because when it's hot, it can't get warmer than the coolant
Ask any pilot about carb icing........it has killed people!!
