Damn, the few extra bucks in my pocket were burning a hole - and now I know why! I’m always a sucker for the subtle details . . . . . .😬
BTW, my wife says to say ‘thank you’ for bringing these to my attention. Um. . . was she being sarcastic?
I wonder how the lacquered covered cloth will hold up with all the heat of a Type I mill ?
I actually won a set of these from ReinCarNation (RCN) awhile back. I don't think they are designed for air cooled engines. I ordered a set for a '67 AH 3000 and gave them to a friend of mine for his restoration. There are lots of quality silicone rubber plug sets with the cooling tin sealing spark plug boots.
Wonder if they have magnetic suppression ignition wires so that I wouldn't have to use resistance spark plugs. I was reading in TheShamba one has a slight decrease in spark with a resistor plug design.
