Or you could go high-tech and put injectors on it - course then you'd need some unreliable electronics and a bunch of other expensive junk to make it work : )
Well if we are going that far a real Honda with the set up for propane from the factory. Just need all the cogs to make things turn.
I know it offends you that are looking to make them all "like when new". But we cannot get gasoline anything like it was when new ether. So I mite just buy a propane conversion if one was available. But direct electric is very doable in my climate even without glow plugs as well.
