Jojo's '70 Stepper

[jojo]

My truck broke down again today. I was two blocks away from my house. I had a few nice people offer to help me push it. I ended up starting it again and drove home.

I can't seem to figure out why it breaks down. I'm betting the plugs are fouled again. It won't idle below 1000 rmp just like last time. It diesels every once in a while (like every couple days or so) when I shut it off. Perhaps the timing? Could that be related to it having broke down on me twice.
