    Re: spark plug question (abrooks)

    Since this is a spark plug question thread, I figured I'd piggyback on:

    The plug chart says QL77JC4 gapped at 0.030 for a 1985 Johnson 140. Does this also apply if the VRO is disconnected?

    Yep, it even applies if the motor has been repainted or if the prop has been replaced.
