Let me give a little more context as I am new here and realize that my previous question was a little short and seemingly unqualified.
In the late 90's I rode a motorcycle across India and through Nepal. During that time I fell in love with these single cylinder, slow running engines that powered everything from generators and pumps, to saws and threshing machines. Everywhere I went in the countryside, I could hear the slow thump of these things working along at all hours. I considered purchasing an Indian version when I was there, but didn't have the time or resources to ship one to the States. Flash forward 20+ years of casual searching and I have come to the realization that these things are pretty rare, especially on the west coast.
38ac, can you tell me more about the one you are rebuilding for sale. I would like to find one and use it to drive a generator.

Thank you,
