Firing order on farmall H

Anonymous-0 · Oct 19, 2009

I have an early farmall H that has been changed from mag to distributor. The plug wires have been pulled off the spark plug side and are not marked. Can someone tell me how to identify which one is which. Thank you.

The firing order is stamped on the block, about in the center, just below the head. It is 1-3-4-2. The cylinders are numbered 1,2,3,4, starting at the front.

I will add to Rusty's info that the distributor (if done normally) has #1 cylinder (looking from the rear of the tractor toward the cap)
at the top right 1:30 position.
Clockwise as follows:
2-1
4-3

You can pull No1 sparkplug near the radiator & bring No1 piston to TDC on the compression stroke. Then remove the cap and see where the rotor is pointing. That's where your No1 plug wire should be installed on the cap and to No1 sparkplug. Then use Jim's sketch for the other three. Hal
