I have a Farmall B that needs spark plugs, does anyone know what it takes, also unsure about year of tractor. Has 4 plug holes and 4 wires.

I believe Autolite 3116 will work fine.

As Jeff says or a D-18 or D-21 champion

I would use d14 or d21 d21 will help it start easier bcause it is a hotter plug. kenny

Recommended Champion plugs are D15Y for heavy duty use, D18Y for moderate duty, and D21 for light use.

Using D21s can cause preignition problems if used for extended periods of heavy duty use.
