Need help Getting Ford 3400 Running

I need help getting my Ford 3400 back up and running. I just recently purchased the tractor and it was running well. The previous owner replaced the starter and starting solenoid. In the process, he pinched the resistor wire between the starter and the bellhousing. (unknown to me) When I got the tractor home I used it a bit (maybe 3 hours) and the tractor wouldn’t start. I heard sparking near the starter. The lugs on the solenoid were all loose and I discovered the pinched resistor wire that was shorting out. I took the starter off and cut the stripped/melted ends of the resistor wire and soldered it together (removed approximately 3 feet). The tractor started and had no issue running. I parked the tractor. When I went to go move the tractor the other day, it started but the rpms would not come up and it coughed and stumbled terribly. I jumped the resistor wire with 12v non resistor wire and that did not help. I drained the carb and checked the sediment bowl. Plenty of flow through both.

I ordered the basic tune kit with points and condenser from YT and I ordered a universal coil with resistor: http://www.yesterdaystractors.com/D5TE12029AB_Coil-Universal-12V_10275.htm.

I plan to pull the plugs and clean them and check the gaps. The wires all seem to be in good shape

Is there anything else I should replace or look at that could be causing my problem?

If rpm wouldn't come up I would look at
fuel not ignition

I know I am getting fuel to the carb and it is all new 91 ethanol free gas. The sediment bowl is clean and the carb has been drained and refilled.

When it is running and stumbling, if you pull the choke out, it stalls out. When you push the choke in it clears out and continues to stumble and run rough.

When you cut 3 feet out of resistor wire you changed the resistance, most likley burning points, damaging condenser. You then installed new points, condenser, and coil with RESISTOR. You still have the resistor wire in it. Jump 12 volts direct to ingnition system, problem will most likely go away. If it does, remove resistor wire replace with normal non resistance wire.

I plan on removing the resistance wire when I change the coil with resistor on it. Would the points and condenser burn out that quickly?

You ran it for 3 hrs, that might be long enough to burn the points and take out the
condenser, just a thought and what I woukd try.
