I picked up a Ford 8N with a side mount distributor. It won't run. The people I bought it from replaced the distributor and coil. They couldn't get it running. I bought it and found a stuck exhaust valve. I had to pull the head to do it. I also bought a 12v conversation kit for it. I put everything back together. Seem like a weak spark to me. Also the timing was 180 out when I got it. Followed the manual to set it up. Tractor will not fire. Read on here how to set the distributor with a meter. Turn it over and it seems like a weak spark. It's doesn't even won't to start. No backfiring. Also I noticed the resister that came with the kit. Was smoking. I rechecked all the wiring. Everything was wired off the drawing. Any help would be appreciated. Thanks
