There is a good rule: If it was running poorly, do not replace multiple items. Just get it diagnosed and then when it is clear what the issue is, and it is resolved, which is a repair and could include things that a normal tuneup would include, but might not. The Firing order is important (side of block). The first place to start is to determine if the points are actually working as they should. With the key on, and the tractor stopped (not cranking) there should be voltage at the coil where it connects to the wire from the key. (or resistor if it has one) If the points (under the distributor cap) are open, there will be almost the same voltage on both sides of the coil. (small terminals) if the points are closed, there will be no voltage on the distributor side of the coil. (that is good) Shut off the key (max time on without running 3 minutes) Look at those points, move the engine by hand (Fan belt and fan)till the distributor cam is opening the points all the way (be careful and do it with precision) the gap should be .020". Clean the points with a lent free paper (folded dollar bill is good). With the coil wire grounded to the block, and with the key on, use a screw driver to touch across the two contacts of the points when they are open. If a small spark is present, they are probably getting correct voltage. Put the cap back on and try to start it.
Please do not give up, this is not easy. My son is 18 and he completely replaced and made operational a 1988 CRX Honda (he now has great respect for His new car.

Today's Featured Article - Timing Your Magneto Ignition Tractor - by Chris Pratt. If you have done major engine work or restored your tractor, chances are you removed the magneto and spark plug wires and eventually reached the point where you had to put it all back together and make it run. On our first cosmetic restoration, not having a manual, we carefully marked the wires, taped the magneto in the position it came off, and were careful not to turn the engine over while we had these components off. We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
