Need advice on how to get a 9N started

As part of a new home purchase I became the proud owner of what I believe to be a 9N 1940 Ford tractor. The previous owner said that it ran, but I cannot get it to stay running. It turns over and tries to start, but never gets going, it runs for about 5 seconds. I have put in new plugs, replaced the gas, checked gas flow and rebuilt the carb. It has been converted to a 12 V system. Any ideas on what to do next. I am a novice on this.

if it has good spark.. check this:

will it run, but stalls when you let off the thumb button?

if so, power to the coil is wired from the starter side of the start switch


can you keep it running by spraying start fluid or gas from a squirt bottle into the carb mouth?

if so.. then the fuel system needs more attention.

post back.

Check to see if you have spark at the plugs. Ground a plug on the chassis, hook a plug wire to it and look for spark. It should be blue and jump a 1/4 inch gap. Post on the 9n,2n,8n forum for more feedback.

Hold your hand over the throat of the carburetor while a helper makes an attempt to start the engine. Should have good suction. Poor suction means low intake manifold vacuum. Do a compression check. Hal

If you have the means, a compression test might give some answers. You'll need a minimum of about 80 lbs to get it running. If the engine is healthy, it will improve as it runs. If you find some cylinders with no compression it may have stuck valves from sitting. If it has compression, give each cylinder a shot of oil. That will help bring the compression up if the rings are dry.

Might take a look at the spark. Check the spark at each plug wire, at the plug end. It should be able to jump 1/4 inch. If the spark is weak or intermittent, the points could be burned or corroded from sitting. Is the distributor in front? If so, remove it to service it. It comes off easily and will only go back one way, can't get it out of time. Since it's been converted to 12v, there should be a resistor in the wire to the coil. If not, the points will be short lived. Look things over in there carefully, be sure everything is assembled properly, not complicated, just has to be right to run right!

Hope this helps.

Checked spark on two of the plugs. Spark on both was weak and did not spark on very turn. I am guessing the points are bad. This tractor has side mount distributor, are the points the same as a front mount. I cannot find a serial number on the tractor I am guessing it is a 9 n.

Great information, thank you. I know that the hot wire goes directly from the terminal block to the coil, I am guessing that the points maybe the problem. Ideas on type of resistor I should install?

I will do more troubleshooting tonight and give you some feedback.

This is probably an 8N with the side distributor.

Since it has the side distributor, the coil may have already been changed. Look it over and see if there is a number or voltage indicated on it. If it's a 6v, a 1.8 ohm ignition ballast resistor should work. If it has a 12v coil, it's probably ok without a resistor, still check for numbers and try to find out if the coil has an internal resistor.

Also check the polarity of the coil. Assuming it now has an alternator, the system will now be negative ground. The + terminal will be connected to the ignition switch, the - terminal will go to the distributor.

The points are different for a side distributor. They are available on this site, at Tractor Supply, or a real auto supply can order them.

While you're in there, feel for side play in the distributor shaft. If the shaft and bushings are worn, the points won't stay set. Also see if the centrifugal weights are free and will spring back when released.

For now though, you just want to hear it run. If it proves to be a useful tractor, might look into electronic conversion, new cap, rotor and wires later.
