And, yes. It would be much easier to work from a cogent list.
I know there was one guy looking for electric start R165s. I like that idea, too, just for the sake of novelty, if nothing else, so I am purchasing a couple of those for myself, in this shipment.
Post the engines you want, and I will ask several suppliers for a price. I'll set a date for payment (very soon, because I want to get my other goods soon) and we can figure out receipts and whatnot.
I am still working with a supplier to prototype air compressor parts. My guys were working the wheat harvest and providing machines for that, so were/are busy at the moment.
