  • The restoration is complete but I can't get her to fire. There's fuel in the carb and fire at the plugs but she won't fire. Points are clean and gaps are correct. She turns fine but won't fire. I am stumped. All suggestions welcome.

  • I hope to solve the riddle tomorrow. In the meantime, here is a pic taken in October prior to the installation of the wiring harness, tank and other assundry parts. It's all together save the fenders, hood and front cowl at the moment as it's alot easier to work on with the fenders off.

    I'll post a more current photo after I shoot them later today.

  • Is there any chance you flooded it while trying. They are almost impossible to start if the plugs are wet. Burn the excess gasoline out of the plugs or replace them if wet.

  • Check fire at the plugs with a plug that has a gap of 1/4 inch.. If it fires you have a fuel or air problem.. You need a really good spark on these old tractors. JMHO

  • I don't see where you say that you used your multimeter and tested voltage anywhere. That would go a long way in figuring out the problem-if you have solid spark at the plug wires and the timing is correct, that leaves only fuel/air.

  • If the points look OK and the plug wires are correct, first thing (magic trick) I would try is to drag a folded over a well worm one dollar bill back and forth between the points while they are closed.

    Hey, you get to keep the dollar and it was a freebie attempt.

    It worked on my JD once.

  • Hi Mike. What are you restoring? What Ford, what engine? Staying 6 volt or going 12 volt? Have you tried any starting fluid? Gas in carb does not necessarily mean it is getting to the cylinders. Help the guys help you.

  • Re: Stumped
  • 1958 861 Powermaster, 172 cubic inch Red Tiger 4 cylinder gas engine. 6 volt. Tried starting fluid in carb and in spark plug ports. Nada. Engine was running fine when I shut it down a few months ago to clean, repaint and restore. I simply removed the spark plug wires and wrapped the distributor. Coil is new. Plugs are new and gapped correctly. Firing order is 1243.

    I rechecked the points earlier today. They are new/clean. No burn marks and flush. Gap is .025. I was thinking it was a timing issue so I checked no 1 cylinder and its compression stroke is pretty much right on the #1 distributor cycle.

    Thanks.

  • Re: Stumped
  • I would check for power to coil.
    If you changed the points, I would make sure points connection is not grounded out.
    If you have power to coil and still no spark at plugs, I would try a different coil and check for blown fuses.

  • Check for plugged air cleaner or exhaust.

  • Re: Stumped
  • Pull off the cap and watch the points as cranking. There should be spark at the points. No spark? File the points.
    Got spark?
    See if spark comes out of coil.
    Coil sparking?
    Check plug wires.
    Spark from coil but not plug wires?
    Cracked rotor shorting to ground.
    Should take a few minutes to eliminate the stump .

  • Re: Stumped
  • Ya, Agree with Bruce, Go right down the line ending with the plugs checking for spark.

    later,dave

  • Re: Stumped
  • CW? Didn't get the time to spend on Friday evening or Saturday. Today we are digging out. So perhaps tomorrow I will get to spend a few hours working it out.
