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 - Show Coverage: Journey to Ankeny - by Cindy Ladage. We left Illinois on the first day of July and headed north and west for Ankeny, Iowa. Minus two kids, we traveled light with only the youngest in tow. As long as a pool was at the end of our destination she was easy to please unlike the other two who have a multitude of requirements to travel with mom and dad. Amana Colonies served as a respite where we ate a family style lunch that sustained us with more food than could reasonably fit into our ample physiques. The show at Ankeny
