well, then. in that case I would advance the sucker and give it a crank. you'll know if it's too far advanced, the starter will tell you.
have fun with the cameo while waitin for parts. got pic of that thing?

I was poking around in my spare parts bin for something else, and what did I find? A brand new coil I was unaware of...

threw in the new coil, turned it over while pumping the gas pedal, and the engine started up and stayed running at a high idle!

The coil I was using ran another truck, but I guess it just wasn't enough for this particular setup.

I suspected the spark, you all suspected the spark, and it was the spark. I don't have the radiator on so I only let it run briefly, but I consider that a success for now.. once it's reassembled, which should be sooner than later now, I can play around with the timing and idle.

Thanks for your help gentlemen!

Update: I found the source of the high idle, I left off the pcv/power brake vacuum fitting so I had a massive vacuum leak. I re-installed all of that, and then it wouldnt start again. I advanced the timing and it would run, but not idle. So I have more adjustments to do, but definitely progress.

Yippee
Now you are coil rich, better buy some more trucks so you have something to use them on, haha

Cool enough, now on to bigger and better things.

Glad to hear it fired up. You may need to open the throttle plates to get enough air into the cylinders when you get back to it.
