47 V8 ignition mystery

[FlatheadTed]

Looking at Henry first post he says the cam was so worn he couldn't set the points, in all the years I have been doing distributors I have never seen this I have only seen points that are badly made and dont set up ,he said it was running fine prior .They stopped doing this on Air Craft because of introduced faults .I have told this story before but I got called out to to a 36 v8 were it had a bad mis he changed carbs ect he .I took my Carb my dizzy wires (known to be good ) the miss was still there on # 6 it compression checked good, I pulled a plug and noticed the valve not going down he pulled the manifold and the top Guide keeper was stuck in the spring . he assembled it and said it still had a mis I suggested that he had introduced dirt into the crab, sure enough!
