Your timing should be set at 4 degrees before TDC. 0 is not good, 8 degrees before is way too far advanced & will cause spark knock like you read about. 80-90 PSI compression is not good at all, it will likely skip intermittently on 1 or more cylinders. Don't expect any power out of that. You a...

Your lack of power after tinkering is due to your timing being retarded too much. It should fire at 8 degrees before TDC. On the smoke issue, unburned gas usually results in black smoke. Burning oil usually results in blue smoke. White smoke usually indicates water. From what you describe, I'm gues...

OK guys, sorry I have been really busy and my internet was down for a while. I did get a chance to look back into some things. We checked compression. Had 80~90 psi on all 6 cylinders with the throttle open. I know this is a bit low (120 seems to be the norm) but we figured it should run with that. ...

"...after 2 hours trying to figure out how to even start it..." Should we reveal the secret, guys, or is it still classified? Oh I figured it out...I laugh now, but I just imagined in my head the number of people throughout the years that did the same as me If the engine in your truck is ...

OK, me and my buddy have gotten our hands on a '52 (I believe) M37. I have to say we were impressed with this american made machinery (this truck is almost 30 years older than myself). I know very little about machinery of this era, and after spending 2 hours trying to figure out how to even start i...
