  • 8N won't start after warm up
  • My 52 8N cold starts easily and runs great until I turn it off after warming up. It just won't start again until it cools down. Any suggestions? Thanks.

  • Coil going bad or bad connection to coil. I would try a new coil. I keep a spare coil just to use to eliminate that problem.

  • Since you said the words, "...I turn it off", not "it dies", I will go off in a different direction than the others. Suspecting a worn out low compression engine, I'll expect that if you pull start it that it will crank up and run fine. If yes, do a warm compression check.

  • Check gas tank vent and replace condenser.A bad condenser can mimic gas problems.You should have a spare condenser and points on hand.

  • 6 volt or 12 volt?

    Donít guess at the cause of the problem; guessing can get expensive. And leave you breathless chasing every guess.......it could be this, it could be that......just troubleshoot the problem and leave the guess work for buying Lottery tickets.

    As soon as the tractor stops running, not 5 minutes later, check for spark and fuel.

    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?

    When is the last time you changed the points, plugs, condenser, rotor & cap and set the timing?

    Ever checked compression?

    * 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. https://www.amazon.com/AMPRO-T71240-Energy-Ignition-Tester/dp/B00A8FO87S/ref=sr_1_fkmr1_4?ie=UTF8&qid=1513273147&sr=8-4-fkmr1&keywords=ampro+spark+checker

  • Re: 8N won't start after warm up
  • Donít turn it off. Sounds like an electrical problem.

  • And the other 2 questions were:

    When is the last time you changed the points, plugs, condenser, rotor & cap and set the timing?
