    Prop change?

    Ignition point

    I have no spark in the bottom plug of my 72 9.5. After inspecting the ignition points I noticed that one of them is completely closed and there is no gap. I tried to adjust it with the screw and at the farthest setting it is still touching. Anyone know what to do in this situation?

    Bottom plug won't fire

    I have a 72 johnson 9.5 that was working fine last year and I went to fire it up today and nothing. After some inspection I found the bottom plug is not producing a spark.

    72 Johnson 9.5 prop

    The stock specs for these are 8-1/8x8. Websites recommend 8-1/4x8. Would I need an adapter or something to run 8-1/4 or would it fit no problem. Also, a friend had one with these specs in plastic. Would a plastic prop of these specs work or not at all?
