Roger you are not using your tractor very much. Your 27 years of ownership and just at 5000 hours is only 200 hours a year. Mine would see that in a litte over a month. It had over 10,000 hours on it before I started to have troubles with it running.
I know how to make a gas engine run. I could not afford to run HIGH test gas in the fuel hog. Was using two tanks a week as it was. It would run better on the Premium gas. I bought 500 gallon and ran it. The trouble was the darn fuel. The economics just did not justify the higher fuel cost per gallon per hour of usage.
I had the Zenith carb. I switched it over to electronic ignition. I tried just about every spark plug that would fit the head. If you ran it a week on a set of plugs you would be lucky. IF you leaned it down to where it would not foul plugs it would die half the time when the governor kicked in.
I bought this tractor in the late 1980s with around 2000 original hours on it. I used it everyday to feed cattle and hogs. In about 2000 I started to have issues with it running. It now had over 12,000 hours on it. So I figured it just was worn out. I tore it completely down. Replaced the valves, guides, ground the seats, new sleaves/pistons, ground the crank, all new bearings, replaced the carburetor and a new distributer. It did use less oil but would still foul the plugs unless you ran high test gas in it. Even then it was not a great running tractor.
The issue is in the combustion chamber design. I have some friends that made a JD 4020 gas pulling tractor. They made a ported, cross flow, higher compression head for it. It runs like a sewing machine. Just too bad it needs Racing fuel to do it. LOL.
I am glad some of your guys get along with a GAS 20 series JD. I will never own a another one I have to keep and use daily. I will buy an sell one but not keep it to use.
