Farmall M 22 degree distributor parts

newtattoobob · Feb 18, 2019

I recently rebuilt my M and installed the over bore step head pistons. I am searching for the parts that originally came in the firecrater kit for the distributor to change it to 22 degree advance. My current distributor is a 40 degree and it runs ok but seems to not idle the best. Any help would be appreciated!

First thing you need to know is what condition the weights and pins are in on the advance. If they are worn out you probably better off to find a different distributor. A 300 has 22 degree advance. If weights are ok, I would just fill in the limiting hole in the plate and do some bending on the spring ends. Get them so springs keep it fully retarded and then the fun begins.

You need to mark the pulley for 22 degrees before top dead center and with a timing light keep playing with the length of the hole and tension on springs until you get a nice gradual advance from idle speed to full 22 degree advance at 1450 rpm.

I measure the hole and do some math as to how much to fill it in for starting point. Liquid steel works fine to fill with. Takes time, saves money.

The plate shown has the degrees stamped in. The 20 degree has the hole shown, the 30 degree has a larger hole, the 40 degrees has a slot. What is constant in all three is the clockwise side of the hole/slot. The amount of travel comes from the left side of the hole. My 20 deg had other problems making it un-useable so I converted a 40 to a 20 by welding on the side of the pin instead of reducing the slot in the plate. When checked with a timing light after installing, it had about the 20 degrees of advance. If want to modify the plate, weld up the left side of the slot till it is a hole that is the same dimension as the width of the slot. The last picture shows how the movement is reduced by the material I welded on.

Trying again with less photos:

Thank you for the pics. I'm going to try it and let everyone know how it goes. Im going to try it with jb weld since I don't have access to a welder.

I may have an extra few 22 plates if you need one

I'd be interested in getting one or two of those 22 degree plates if you'd like to sell them.
How could I reach you ?
thanks

mccormicksw4 · Apr 3, 2019

I will sell them but I don't see your email on here. maybe you don't have enough posts? I dunno
