LA 318 Dying when put in gear and high idle issue solved!

I can top that. 318 all of a sudden when started cold, shook like the motor was going to come off the mounts. I played with choke to no avail. I tried a few other things, checked timing chain etc.. For some reason when warm it stopped the violent shake. I changed the coil and no longer have that cold violent shake. So many things can drive you crazy trying to troubleshoot and sometimes you get lucky and find the culprit. I also tried carb with a good one and no help.
