8N 1952 sputters, then dies after a while at hiher RPM with load.

Tom Branum I have been tinkering with this 4 cylinder Ford engine since I bought a 1929 Model A car 60 years ago. Now have 2 8Ns; a 1948 front mount (have kept it running for 32 years) and 1952 side mount (have used it to mow pasture for 5 years). It started to sputer and die, so I replaced coil (twice), condenser (twice), plugs, wires, and points. Starts fine, but has an irritating sputter (miss?) no matter engine speed, distributor setting, or carb setting. Still dies after a few minutes under load. Stiil has gas to carb when it dies. Any reasons other than fuel or ignition that could cause this?
mark sr Have you run a compression check?
Bob in KS 6 or 12 volt?
some possibilities:

Where are you getting your points? Cheap points that do not maintain .025 gap on side distributor or .015 on front distributor will cause similar problems.

Dying after a few minutes could be ignition switch failure. Check by jumpering the switch or terminal block.

12 volt conversion with defective or off value resistor between switch and coil input

Cracked and/or corroded wiring or connections


kely williams i have 1950 8n ford tractor sidemount dist. i installed a 12 coil with built in resistor. with the old coil voltage to dist was 8 to 9 volts which burned out condensor. with new coil with resistor voltage is running .56 volts to distributor. tractor starts and runs great. is this enough voltage for the distributor
