I HAVE A 1949 FORD 9N THAT HAS BEEN NOTHING BUT TROUBLE FOR TEN YEARS. THIS YEAR HAS BEEN THE ABSOLUTE WORST. SO FAR THIS YEAR I HAVE REPLACED: RESISTOR, COIL,REGULATOR, POINTS(TWICE), CONDENSOR, ROTOR, DISTRIBUTOR CAP, PLUGS, PLUG WIRES, MANAFOLD GASKET, AS WELL AS REBUILDING CARBORATOR, REPLACING SCREEN FILTER IN BOWL, GASKET AT TOP OF SEDIMENT BOWL. GUESS WHAT-- THE DAMN THING STILL RUNS 20 MIN AND STALLS. WHAT ELSE CAN BE WRONG?

I know your situation well. Went through it with my 9n. The guy I bought it from could not get it right, so he sold it to me. I never ran it long enough for it to start failing like yours is doing. So I bought it. It was cheeper than others, but ran rough. All is fine now. Someone below said to isolate the problem. Thats right. It turned out I had two problems at the same time. Rust in the tank kept clogging the filter in the tank. Also the points were too close and would close just enough to cause the missing and stalling. I though they were ok but must have missed it. If yours is just stalling right out at some point, without missing alot first, then it may be the tank filter stopping up, or atleast fuel related. I blew air through hole up into the tank. Not high pressure. Just enough to clear the rust away. Then I could compare the correct fuel flow the what I ahd before.If you have good flow don't do this. It will spray gas into the air. Very bad. I was told to spray WD-40 or equiv into carb intake when it began to fail. If it ran better it was fuel, if not it was ele. Don't give up. These are simple machines. You will find the problem.

according to your list the only thing left is the resistor on the junction block, the ignition switch, and removing the fuel valve to check fuel flow thru the openings, i had virtually the same prob you describe,culprit was rust in the tank and fuel valve. once these were replaced, was to far gone to clean and reuse, i have had nothing but smooth running please from it. a 46 2n

RON, you need to isolate the problem first. it's either electrical or mechanical (fuel supply). With ANY piece of equipment, just remember, the rule of thumb is that the electrical system is the weakest link. Next time it dies, put tractor in neutral, grap plug wire off one jug, stick in an extra sparkplug from your pocket and hold it against the engine block. Crank engine and watch for the sparkie. If you got spark, look at fuel system. There are 3 screens or filters involved in the fuel supply system. The tank, the shutoff valve, and the carb. I suspect a bad ignition switch. Jump switch on the backside as per previous post to verify. Be careful. My 2 cents worth.

Have you checked/cleaned/replaced the connection between the sediment bowl and the gas tank? How about the gravity feed line to the carb? How about the little screen where the gravity feed line connects to the carb? How about the gas tank itself? Any of these areas could have rust or other blockages that prevent proper gas flow to the engine at normal operating temperatures and under load.

When you say stalls, runs, stalls, runs. Does it start right back up? Or does it have to sit a spell?

I've not had personal experience with this, but I've read on this board that it is possible for a defective ignition switch to cause stalling when it heats up after a period of running. You may want to do an archive search on this subject. I don't think switches are terribly expensive so it may be worth a try. Good luck!

Regards,
Darryl

It's easy to test. Just take a jumper wire with you next time you use the tractor (14 ga wire with alligator clippies on each end). When it stalls, clip the wire to the two terminals in back of the key switch, thus bypassing the switch altogether. If it runs while the jumper wire is in place, you've isolated the bad guy! By the way, if it's a 1949, it's an 8N not a 9N. Just quickly, 1939-1942 = 9N, 1942-1947 = 2N, 1947-1952 = 8N. Good luck with it.

Had same problem with 39 9N. Replaced all the same things you did. The last thing I did was replace points, rotor, condenser, and distributor cap. I'm sure that was part of my problem when it got hot from working under load. However, it stalled again after working with a medium to heavy load. I got off the tractor and looked in my fuel sediment bowl. At the screen area was a large flat air pocket. It was not getting the fuel it needed. Simple to look at and somewhat simple to remedy. Removed the shut off valve from the bottom of the tank and found the screen in it was full of loose rust particles.(Suggest you have given thought to corking the hole left in the gas tank once the shut off valve has been removed and to work while the engine is cool) Put it back together and it ran fine. It could still not be getting the proper fuel amount without the air bubble being noticed.
