The truck was running fine except for a couple of sooty plugs. It was rebuilt about 4K miles ago and I thought it was about time to adjust the valves.
I adjusted them to 10 intake and 18 exhaust and it STILL won't start. I did get a tiny bit of popping through the carb though. I just can't believe that they are still to tight..... I am going to try 10 & 22 next.... This is incredible..
