I have this 1941 Farmall A. Been nothing but problems sorting out since last late summer when I got it. Would just cut out and die, and would not restart. Has had new: Points, Condenser, Rotor, Cap, Spark Wires, Coil, new Coil Tested, spark plugs, regulator, generator rebuilt, gas replaced, another new set of points and condenser...
Lastly, I have replaced the 6V battery as it would not hold a charge.
Things slowly have gotten better. But lastly it would not stay running when it warmed up under load. So I got a carb rebuild kit, cleaned the carb, soaked it for 3 days in the can of carb cleaner, and did the rebuild. Installing the rebuilt carb; in "testing" under load when it warmed up it would begin to die and if I choked it, it would continue to run. So I decided to purchase a new carb...
There was always a governor surging or hunting problem; so I installed the new carb, ran without adjusting the linkage and the surging started under load quickly and now it's so bad with the new good carb, I cannot keep the tractor running with the tractor under load. So adjusted the linkage to the carb and made sure it's not binding on the block also, but same surging or hunting problem. If I grab the linkage from governor to carb, it stabilizes and runs fine. I can run the engine with my hand on the linkage to stabilize it, running fine, wide open, half, or at idle. This surging or hunting happens under low, medium, or full throttle, and eventually stalls the tractor under load if left unchecked by clutch. I can unhook the "load" (harrow) and drive the tractor into the shop OK.

Since I'm at wits end, any intelligent suggestions and help as to what to do next is appreciated to solve what I think is the last problem in this tractors complex issues...

Today's Featured Article - Search For Spares - by Anthony West (UK). Following on from the aquisition of the old Fordson F, I was very much in need of spares. As a novice though I didn't appreciate the fact that there were so many Fordson tractors made, that all the other makes seem rare by comparison. As far as I was aware a fordson was a fordson and it was only through trial an
