pul 1 plug at a time in order and see what cyl is missing.

swap that plug with another and see if the miss jumps.

A miss can be many things. #1 a wore bushing in the distributor causing one plug to fire poorly. #2 a bad spark plug. #3 a bad intake manifold with say a pin hole. #4 a sticking valve. #5 a bad head gasket causing loss of compression on one cylinder and the list can go on. So the first thing to do is as sound said and find which cylinder it is then check for the stuff I said

Up date on 8N miss the problem was one of the wires going to the front mount distributor was loose.Thanks

My 8N was starting OK but running rough soon after I brought it home. Had done some mowing and seemed to be OK, just a bit rough. Went around to the right side of the tractor (as sitting in the seat) and found one plug wire completely off the distributor. Don't know why it even started all those times. Pretty amazing machines.
