Great Advice Mike.
1. I lost TDC. I'm fairly certain (but didn't take a picture) that TDC was at the 0 mark on the balancer when I installed it. I've rotated it a little out of whack as I tightened the crankshaft bolt, but I think I can spin the engine backwards to where it goes. Every two rotations is TDC, right? I seem to recall that by staring at the keyslot on the engine.
2. Burp the radiator? Hmm, didn't know that was a thing. Guess I need to fill it all the way up, right? There is usually an air gap in the radiator, right? I found this funnel, but it doesn't discuss "burping": Amazon product
3. Using the key to prime the pump using the starter is a great idea but... won't that inject fuel? That's going to result in a lot of excess fuel unless there is some way the computer knows that combustion hasn't occurred.
You may have the distributor put in wrong and wrong timing. The way I do it is I pull the #1 plug and put my finger over it. When I feel air over my finger I put in a screw driver and gently set it against the piston. I then turn the crank slowly as i watch the screw driver reach it's peak and as it stops rising I look at the crank pulley, it should read TDC. You now know you are at top dead center for #1. now you pull the distributor cap and make sure the rotor is facing, ah ****, what cylinder is it guys? Too much to drink and I forgot. Dang wisky
This is what mine looked like, rotor at #1 plug wire.
