Good for you. This past fall I had a chance to pickup a Rumely L for parade use, but it was a bit pricey come auction's end. Needed a little cosmetic work, but the one thing that jumped out at me was the low compression on one of the cylinders. Ended up having to pull start it to get it to fire up. Man them things are loud. Some fella showed up heck bent to buy it, wasn't going to be out done, and drove the auction price way too high for my blood. He even pulled out a tape measure to figure out how much he was going to have to cut out of the supports to lower the canopy to fit it in his garage. Hey, it was his money, not mine.
Well good for you. Seems like you picked a swell winter project. Much good luck and success.
