: I recently purchased a Farmall H, I believe to be a 1950 vintage. It currently has Champion D15Y spark plugs. Are these the right plugs? If so what gap should they be set at? The tractor turns over strong, but will only start when "pop" started. Once it is running it seams to run very well, it just won't start on it's own. Any suggestions would be appreciated.
In all of my IH tractors, I use a D-21 plug. The gap should be .025!
