Do yourself a favor and READ up the KETTERING IGNITION SYSTEM... it will give you a basis for troubleshooting... Where you should find voltage etc. You will never see 6 volts AT a spark plug... (There *IS* an air gap IN the distributor..)
Better yet, get with an old-timer kind of mechanic and have him do you a session of Show & Tell on YOUR tractor. It's worth your time and gain you some BACKGROUND.
