I have a 1943 John Deere model A I have been tinkering with. Its never been easy to start and never ran quite as well as it should. Would run uneven at times but didnt sound like an all out miss. It sat for quite some time before I got it so I figured the carb would be suspect #1 but its very clean inside and all the passage ways are open. Suspect #2 was of course the mag. Cleaned the points and checked the gap. All seemed fine but when I tested it by turning it over by hand I noticed that spark seemed to be weaker on the lower socket than the top and it would sometimes fail to fire when it should have. I hooked up an adjustable spark tester and sure enough the top will throw a stronger spark than the bottem but will also miss here and there with the tester. By far no expert on mags but I would think that spark would be the same on both sockets weak or strong. Both sockets and all contacts inside the cap are clean.
