Go to the Allis forum and do a search on distributor, points and spark.
Not sure of your situation or what updates were done to your WD. There are so many combination of things that go wrong but the good news is that they are all repairable. I would start with the points, cap, rotor, condensor . Replace all first. Get them at an online Agco dealer unless you have one locally. I've used the generic/ cheaper points, etc from local tractor supply stores and either they don't match up right or the cap and rotor have a lot of play when you try to snap the coil on the distributor. The point gap is .020". Next is the coil - 6v or 12 v. If you change plugs, use Autolite no 85. I put in Champion and they were so-so. The Allis dealer told me not to use anything else but Autolite and my wd45 is running like a champ right now. If you have the original wiring harness, make sure the wire running to the coil connection is good. Use no 10 stranded wire if you replace it. Allis ran the wire over the back of the valve cover and up to the key switch. . so there is a chance it may have burned through and is grounding out on the head. Agco points, condensor, cap and rotor will run about $30 but they last. A new coil ranges from $18 to $37. Check the plug wires while you're at it too. Make sure they are not grounding out on the block. If you don't have one, buy the repair manual. They are available on Ebay for about $15. I use the orange reprint one for WD /WD45. The IT Manual is good too but it covers too many models and gets confusing. Good luck. You'll find lots of good sound advice in the Allis Forum, especially on troubleshooting / testing a lot of these parts. I prefer to just replace.
