  • Spark Plug Wiring Service Bulletin !

    This is an original Engine Service Bulletin from International. Ever wonder why they run the spark plug wire around the back of the carburetor?
    Because of crossfire and damaging the number seven cylinder.
    These bulletins are being shared with us by our Just IH President Todd Munns.
    Thanks Todd.
