Unstyled d

[Jkittle]

I just purchased an Unstyled John Deere "D" and I am working on getting it to start easier. Can someone tell me the correct spark plug in a Champion brand? I thought it was a W -18 which is what fits my styled model "D" but it is too large. Thanks in advance for your response.

I run Champion 525 in my 1936 D

champion W89D is what I have on my '35 D
Napa can usually have them in a day if they don't have it in stock

My 35D I bought auto lite 3077. I've heard they don't make them anymore . I got 3076 in my 37 A and they may still make them. Both are 7/8 thread the 3077 has the wire electrode and. 3076 is made like conventional plugs.
