I appreciate all the responses. The odd part of the spark issue is that it will start every day after sitting for a period of time, usually overnight, run for a few minutes and lose spark. There is still 6.24 dcv to the coil with no spark to the plugs. The tractor has gone through a restoration and is kept inside out of the weather. The following has taken place since the spark issue:
1. Replaced the insulator under the brass concave head screw.
2. Continuity between the the coil pigtail and top of the coil good.
3. Copper strip intact and not grounded.
4. Distributor to block clean and grounded. Points plate clean.
5. Continuity between top of coil and yab good.
6. Spring clip in proper position and condenser wire not grounded.
7. Distributor mounted tight with gasket.
8. No moisture issues. Tractor stored inside.
9. Replaced bushings with no shaft movement side to side. Points replaced, gapped to specifications and checked for continuity when closed.
10.Replaced the Distributor cap, rotor, coil, coil wire and resistor.
I have considered a new distributor or electronic ignition. But I like the idea of keeping the tractor as original as possible.
Would the weights and springs affect the way it is acting? This seems to have started after I had the bushings replaced. Prior to that is was just hard to start because of the sloppy shaft movement and point gap changes do to worn bushings.
