But Mike when I installed my dizzy in his truck, it still acted all retarded with his newer coil. When we ran the stock setup with stock coil, resistor, and distributor. It ran better. I'm really guessing its the retarded newer model coil that's dead. You know Ben go to an Auto zone. If they are smart enough, they can test that coil for you. I use to do it alllll the time when I worked there....
My dizzy works great on my truck. Really!
Thanks alot Ben for letting me use your timing light and letting me have some left over 620 parts. I just went to the junk yard this morning and got me a Mark VIII Lincoln electric fan that I plan to use on my 620 and other stuff I got planned with this new paycheck. I might head back over there for some measurements of your 620 clutch sleeve. Or you can just tell me in a note the measurements. That would be nice!!!
