  • 1952 Ford 8N will not start!
  • My tractor always starts on the first or second turn. Yesterday when I took it out of my heated garage so I could get a friend's truck in. I let it run for 20 minutes outside. Outside temps were at -2F. About three hours later I went to start it and, while it would turn over just fine, it would not even kick! So, I covered it in my driveway and left it there. Yes, there is fuel....yes, I had the fuel turned on....yes, the key was on. I tried it with the normal choke setting and ot was a no go. I then pulled the choke out further but still zero. Ideas??

  • First guess. Flooded.
    If gas was on and float valve leaked. Flooded. Loosen intake hose connection and see if gas runs out.
    Second guess coil or connections to coil. Check all connections for voltage. If key left on over an hour. Coil can overheat. Check points first. Then swap a spare coil to it. An auto coil will do for a test.

  • 1) condensation inside distributor cap
    Pop cap and spray inside with electrical parts cleaner

    2) insufficient vaporization of fuel
    Heat lamp on manifold

  • 6 volt or 12 volt ?

    Front or side distributor?

    These tractors are pretty simple machines; itís usually pretty easy to get them running with some basic troubleshooting steps. You can:

    1. Replace every part you can until it starts or you run out of money.

    2. List every possible cause of the problem and then randomly pick your favorite to check. It could be your coil. Or your ignition switch. Or about 10 other things.


    3. Like diagnosing any other equipment failure, take a step-by-step approach, working from the most likely to the least likely, one system at a time.

    Iíve tried all three approaches. The third one always worked for me.

    I might not be able to tell you why your tractor isnít running, but I can tell you how to figure it out for yourself.


    You could have a spark issue.


    You could have a fuel issue.


    Donít guess. Troubleshoot. See tip # 13 at the link below.


    As soon as it stops running, not five minutes later, you need to answer 2 questions before you do anything else:


    With the bolt in the carb bowl removed and the gas on, will the fuel flow fill a pint jar in less than 2 minutes?


    Next, get out your adjustable gap spark checker * , open the gap to 1/4", hook it up, turn the key on and crank the engine. Does the spark jump 1/4"? Post back with the answers.


    And do not buy a new part for the tractor until you can answer this question: how do I know the part on the tractor is defective?

    Once you narrow the problem to spark or fuel, post back and tell us what you found (and how you found it) and you will get plenty of help to get your tractor running.

    * Don't own an adjustable gap spark checker? Buy one! Not a test light! Until then, take an old plug, open the gap 1/4" ground it to the head & look for spark. Itís not the color of the spark that counts; itís the distance it jumps.

  • Re: 1952 Ford 8N will not start!
  • I appreciate your responses. The thoughts from members here prompted me to do a more thorough check. I found the battery terminals (12 volt) were corroded....my bad. So, I tried running jumper cables from my truck and it started right away. I drove it back inside and removed the battery to be charged on the bench and cleaned all the corrosion from all connections. It then started at the first turn. Problem solved? I hope so. Thanks to all. DED
