Good to know! If my 8N ever needs a tune up I would have been lost.
My boss has a '29 Model A, and it is 1-3-4-2, and at the time I couldn't remember ever running across an I4 that wasn't. But I know there were some old French engines that had the crank configuration different. They had #1 and #3 pistons going up and down together, and #2 and #4 were paired. So they may have something different.
If you know something about tractors, come help me figure out my '51 Farmall Super A!
I cannot get it to run!!!
