Any interests in propane conversion? I have a spare ea81 block laying around and im considering propane conversion just for grins... ive aquirred a book that goes over converting smaller 4 stroke motors but the math should all carry over. ive seen kits for v8 motors but none for smaller. I may use an existing carter webber that i have being a single barrel, or the hitachi seeing that those are more common. other option is just to fab a new one up from scratch, and might be the easier route.... any one ever try this?
