1-800-522-7448 for the real deere manuals cheap. You need to know a lot more than just point and plug gap.

You are missing out. Have the owner purchase the manuals.

 Re: 3020 JD gas standard Delco gaps in reply to buickanddeere, 08-23-2005 08:14:01  
Single point Delco Distributors run a 22 thou point gap. It's a conventional Kettering ignition system. A low rpm four cylinder will run fine with a 30 to 35 thou plug gap with a ordinary coil. Depending on the age of the tractor it will be a postive ground with a generator. The coil's + goes to the dist. If it's a later alternator equiped JD the ground will be neg. The coil's - connects to the dist. Depending on which JD and it's spark plug threads. An Autolite 216 or 3116 are less inclinded to foul. And they are both non resisitor. Odds are the carbon resitor wires are failing with too high of resistance or internal gaps. Replace with solid core wires. Points and plugs maynot be enough. Those tractors equiped with Zenith carbs perform better and smoother on less fuel. A compression check and valve lash adjustment is likely over due. A flat feeler gauge won't work if the valve and rocker tips are worn. The clearances will be wider than intended after adjustment.

 other stuff too, Re: 3020 JD gas standard Delco in reply to buickanddeere, 08-23-2005 10:15:22  
Other things to check is pulling the hose off the carb intake and making certain the choke is fully open. The aircleaner lid can be over tightened and restrict airflow. The airfilter may have been cleaned 47 times and is plugged. The safety filter is not supposed to be cleaned and it maybe plugged as well. Years orf dust and oil can plug the intake piping as well. Too many times farmer bob removed the thermostat and thinks his tractor will run better when operating cooler. Not so. That gasser needs a 195F stat.
