Question: What Should The Points Be Set At On An Eight End Ford Tractor?

What should the compression be on a Ford 8N tractor?

It seems reasonable that the published 8N compression ratio of 6.2:1 therefore should yield a maximum cylinder pressure of about 91 PSI (6.2 X 14.7). However, compression of a gas also raises its temperature, which increases the maximum cylinder pressure.

What do points do on a tractor?

It’s the same on a tractor. The points just open and close on a cam inside the distributor to transmit an electric charge to the sparkplug(s). Just as the points begin to open the coil releases it’s charge to whatever sparkplug is in firing position.

How do you adjust the carburetor on a 8N Ford tractor?

For a new or rebuilt carb, I use the following bench adjustments to start:

  1. 1—Turn the IDLE SPEED screw all the way out and then turn it in slowly until it just makes contact with the pin and the throttle plate is fully closed.
  2. 2—Turn the IDLE MIXTURE screw all the way in and then back out ONE turn from the bottom.

How do you check a Ford 8N coil?

Place the end of the spark plug against a ground such as the engine block. Have someone crank the engine while you hold the plug against the block. If the coil is working, there will be a spark. If the spark seems weak, test with a multimeter.
