AVB, the Victa 2 strokes use the most primitive setup you could ever imagine, a small self tapper screwed into the end of the lead and a rubber boot slipped over it, but they work and that is all that matters
Interestingly enough Norm, Victa only brought in that setup on the last of their full crank engines, and then carried it over to the PowerTorques. Previous to that, a crimped brass lug was used at the HT lead end.
I'd say that what made it possible was going to a silicone rubber plug boot, which don't perish. Wouldn't have worked for all that long, with the older perishable butyl rubber type boot.
