Had an weekend neighbour ask me about his grandfathers 2N about a month ago. I offered to get it running for them since they don't know much about tractors and here and there I cleaned the points, bypassed the ignition switch and cleaned the carburetor. After a bit of fiddling it was running on 3 and not starting bad so I left it at that until they could bring up plugs and wires. This tractor hasn't run in 15 yrs and I'm assuming didn't run well then so I was happy with my progress. This week the neighbour and his shift working son were up for a couple of days so we looked at it together. He had put the plugs and wires on, he seems handy with a bit of direction, and we started it up to run on, 3 cylinders again. Loosened the manifold to release the tappet cover, I think that is a bit of a design defect, and sure enough one valve was stuck wide open. Left the problem with them and 4 hours later it was running on four with the valve freed up and the young lad very happy. Nice people and able to do the work, just weak on troubleshooting. Another tractor saved from eventual wrecking.
