John deere model A spark plugs

[Tstoner]

I'm sure this topic has been beaten to death. But I'm getting close to firing my 1944 A up after a restoration....Hasn't ran in 40+ years. Was wondering what kind of spark plugs you guys have luck with and run in these two cylinders?

Autolite 3116

NGK AB-6 have been working well for us.

For the later model 18MM Plugs I also like Autolite 3116 as its a NON Resistor Plug
ESPECIALLY with a Magneto ignition. For the older 7/8 plugs I like the hotter deep
reach side wire electrode 3077

I have D23 champions in mine. They are a long reach
plug.

this is what i am talking about. them 3116 are not the right plugs. the threads are short and the remaining threads in the head will just get
all carboned up. so have a close look at your head. you need champions or the equvelant as i have posted.

I run Autolite 3116 in my '55 60 & they do great.
