I have noticed that my tractor has been running a little rough latly. It sounds like it is getting too much gas, or it is an exhaust valve sticking. I have replaced all of these things. I have gotten new points that are set right, condiser, rouder, and a new distributor cap. I also rebuilt the carburator and got new spark plugs and all new wires. If someone can help me out that would be appreciated. Thanks
 
Could you be a little more specific as "running a little rough"?? Intermittent missing?? No missing but uneven running (fluctuations in power)? "Rough" all the time?? If not all the time, when: cold? hot? pulling lightly? pulling heavily?--stuff like that.
Long distance diagnosis is difficult without detailed info.
Generally, too much gas will show as heavily dark or blackish exhaust.
If you haven't already, you might put a heads-up on the Deere forum here; another Deere owner would probably be the most helpful. Good luck.
 
It is not missing but it is uneven running. It pulls good and everything, and there is no power loss. There is a little black smoke when you first start it but not much. thanks for your help
