Model U

Bought a U that had been setting for a couple of years (that was what I was told), got it started today and the breather on the valve cover on the rear cylinders was pouring out smoke, I ran it for a few minutes and it did not stop. Looking for causes, it this valves, rings, or a clogged breather, there was no smoke coming out of the muffler. Thanks

Had that on a JS3, broken piston rings. That's assuming that you're talking some real serious smoke.
