Just because you have all those new parts, don't assume that the ignition system is functioning properly. Test it to make sure.
Have you tried checking the spark by pulling the center wire out of the distibutor cap, holding it near a good ground and trying to start? You should have a FAT, BLUISH-WHITE SPARK, THE COLOR OF LIGHTNING ABOUT 1/4" LONG. If it's blue, reddish blue, or yellowish you have a weak spark. Check all the connection, make sure the points are clean and properly gapped, that you have battery voltage to the battery side of the coil with the points closed. If it starts running ratty, put a jumper across the ignition switch and see if that cures it. Ignition switches get high resisitance in them from dirty contacts and that can cause a weak spark. Make sure that you have the correct firing order. Check the timing with a timing light and verify that the advance is working. Are your wires copper core? They should be. Carbon core wires don't work well on tractors. Do you have the correct coil? If you have a 12 V system, you should be using a real 12V coil like a NAPA IC-14SB coil(~$15). It needs no separate resistor. If you have 6V coil on a 12 V sytem, you'll need a resistor to drop the voltage at the coil terminal to 6V to limit the primary current to 4 amps max or the coil will overheat and eventually burn out.
Make these checks sytematically, checking for effect any time you change anything.

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
