Farmall C won't start

Son-in-law and grandson brought home a 1949 C. Apparently restored and painted maybe 10 years ago. Battery was dead and wouldn't start when they bought it. Blew out gas line, cleaned up battery cables, new battery, put in gas. Cranked strong and fired right up. Ran rough for a couple minutes then smoothed out a little---then died and refuses to fire. Pulled a plug wire and can't see any sign of arcing a spark. It's been converted to 12 volt system.

I grew up orange and don't have any Farmall experience. All thoughts and suggestions about where to start are appreciated.
 
Use a test light from ground to the small terminal on the side of the distributor. Crank it. If the light stays on the points are not closing or they are disconnected. If the light does not come on the points are not opening or they are shorted to ground (possibly where the terminal that goes through the side is located). Jim
 
Should be a resistor somewhere to get voltage back to 6 volts at the distributor. They go bad sooner or later.
 
hot wire and crank it. (run a small wire from + post on battery to battery side of coil. if it runs, you probably have a bad wire switch, etc., if it does not run, then points, coil, . rotor button distributor cap, etc.,
 
there you go been converted to 12v that's the problem figuring how they did it got a loose wire or just maybe burned something up start with voltage to the coil and thru the dist till you have fire at the points then spark plug wires and plugs check the valves by removing the valve cover to see if all are working. It ran once so shouldn't bee too hard to get it to start again. You do have gas thru the carb
 
If it sat a while, it could easily be bad gas and crud in the carb. Gas doesn't stay good for very long these days and can clog the carb.
