How to set the ignition timing on 1941 Farmall H

Stevishere · Sep 5, 2011

I have a vertical distributor on my Farmall H. I installed an electronic ignition. When I first had installed the new electronic ignition, it was a little harder to start than before but it runs great!

It used to be just touch the starter and it would fire after about 1/4 revolution.

I loosened the clamp bolts and futzed with the distributor while it was running, made sure I could dump full throttle without any pops.

I would like to make certain the timing is set correctly. I found the (2) registration marks on the fan pully, hooked up my timing light, and I could see the mark, firing about 1" before the register.

Anybody know where it should be?

Thanks!

At idle it should fire on the first mark.

(quoted from post at 20:21:34 09/05/11) At idle it should fire on the first mark.

Thanks Tom. I tried that. The closer I got the mark to the register the harder the engine labored. eventually , it would not even run.

Double check that #1 piston is at TDC on the compression stroke when the mark lines up. Someone could have put the distributor on wrong or mixed up the wires at some point in the past 70 years.

Great points Tom. I will check those out as well.
