As I reported earlier, the truck engine stumbled then quit as I got it back to the garage after driving it the other day. Went out a couple of days later and tried to start it and finally called "no joy" after many attempts. Long story short, I think it was the points (pics attached). Ultimately, I replaced everything. New ballast resistor, points, condensor, coil and plugs. Then I re-did the static timing and the idle. It fired right up! It sounded SO much stronger! It did, however, continue to belch the white exhaust.... Tomorrow, I'll have a stovebolt visitor to help me fine tune the engine. I'm really looking forward to it! More to follow...!
