Thanks for your detailed instructions. I went out this morning to start the tractor and because it was so cold (20) it wouldn't crank fast enough to start. The battery is about 6 months old. I then got my farmall h out which has an 8v battery and jumped it off of that. Fired right up and ran really smooth. As soon as I removed the jumper cables it started running rough, so now I know it's not the carb adjustment. The ammeter reads that it's charging, but obviously has weak spark. Any ideas? Thanks!
