here's something weird. The truck now has spark and starts just fine. I was over in the spout connector area wiggling wires and stuff around,when I heard the sound of a small electrical spark,tested for spark at the plug,had it,and the truck fired right up!! Now I have to get a working test light and see where the timing is,which I think is the reason the truck died in the first place several months ago,I think it jumped time and died because I had to move the dizzy to get it started after I got it towed home a few months ago.
