Dan, not really sure what they were originally used for. But I do have one. I was going to fix it up, (its been ...dormant... for quite a few years) but if you want it I could give you a deal on it. The following Items I have, but are pretty much useless. Tank (rusted to hell and back) Muffler, similar condition ( you can get a screw in one from lowes for cheap). I'll throw a new gasket on the crankcase and start assembling it when I can. I can get an original tank on there, or I could get my machine shop to make an adapter to run a solid honda carb I have. I will say I cleaned the block and it turned out looking nice, the Valves and all are still in place. Its a clean, single bearing block in good condition. Let me know if your interested. (now that you know its life history) 8]
