Hi guys,
I got a 1952 12v 8n a couple years ago to brush hog some new land. Initially it ran fantastic. Started right up. Plenty of power. Happily did whatever job I asked. Then one day cutting the field it started to act like it was bogging down in the tall weeds and losing power. I would slow down and it would kinda get along, but after about 30 minutes it started to kinda chug then died. It restarted right away, ran about 10 minutes and died. Restarted again, same thing. I managed to limp it back to the barn and called the guy I bought it from who suggested maybe the coil burned out. Bought a new coil, tractor fired up, ran okayish about 5 minutes, chugged, died. Tried to restart, would not restart. If I try to start it in the morning it will fire and chug terribly for about one minute sputtering black smoke and stinking up a storm, then it dies and will not restart until I try again the next morning. It wasn't long before I found this forum and started digging around trying to learn as much as I could. Maybe not so good at that either.
I put in new motorcraft AL7c plugs, gap at .025. I have good spark on all four plugs.
I pulled the side mount distributor cap. Rotor and contacts look good. Points and condenser look new and clean with a spark if I open it key on.
I have battery voltage at the point pass through with point open key on.
I have okayish fuel flow at the drain plug under the carb, just a little over 2 minutes to fill a pint.
I pulled the carb apart. Everything looks clean and in good shape. I did go ahead and clean it with carb cleaner and blow it out best I could with an air compressor.
Currently, it does the same thing it did before I tried all that. Starts in the morning, chugs terribly for about 1 minute, dies, will not restart.
I really need to get this field cut, but not looking good this year.
What am I overlooking? What did I forget? Help!
