This thread brings back memories. That engine wasn't stuck too bad if you got it freed up that way, Dave. I've been known to pull the head and crank and drive pistons out of the block with a 2x4.
What the guys told you is spot on. As far as the crank and spark retard lever, I have a scar on the point of my chin when I forgot to set it correctly and the crank pulled me down onto the radiator cap. Fortunately it didn't have a fancy ornament on it. I did see stars for a second.
I drove a Model A for 6-8 years as a kid, so if you have some specific questions feel free to call me. I still remember lots of the quirks. But they're pretty simple machines.
Oh yeah, If you get it running stay away from those copper spark plug connectors. I've gotten a few bruises on the back of my wrist from getting bit and whacking myself on the radiator support rods.
