Checked the compression on my 2N today as it is not wanting to start. Appeared to be getting spark also appeared to be getting gas, but not 100% sure. Plugs were fouled, black deposits. Compression test ran today and as follows stating with cylinder #1 100, 75, 110, 100. After adding a little oil to #2 it came up to about 85 to 90. Thinking I have worn rings at least in #2 cylinder from the readings. However would these reading prevent the tractor from starting and running? Put new points in distributor and am soaking plugs in lacquer thinner overnight as someone suggested. Will try again in a few days.
