Long story short, old motor sat around for a few years, rings froze, I did a complete rebuild of the bottom end. I've got it all back together, trying to make her fire. Only problem is that it's firing out the carburetor. Obviously it won't start. If you hold the throttle open, it sounds like it is backfiring on every cylinder as it cranks. I checked the timing and it's fine. I will be double-checking to make sure nothing funky is going on but it should be fine, The number 1 intake opens when the rotor is in the #1 firing position, so the cam is in correctly. The distributor might need some minor adjustment typical of a rebuild, but it should be close.
I had to replace the motion sensor and rotor, since all the leads were corroded. I also replaced the coil. There's nothing in the book about it, but I read somewhere that there is a procedure you have to do when you install a new motion sensor, but I'm not sure. That might have been for newer motors.
I'm also wondering if the ICM is bad, but I read somewhere that that is a solid-state module, so the likelihood of that failing is really minimal. Plus it's like $600. Other than that, I'm at a loss, so I thought I'd ask the pros.
