who would know the spark plugs used in this motor.<br />I have a manual and it does not have any listings.<br />It tells you about the plugs but not which plug is for that motor. :confused:

Champion QL77JC4 set at .030.<br /><br />Alternative: Champion L76V...surface gap.<br /><br />The QL will work fine.

There is no hook and the surface is pretty flat. They work best on motors that are run hard. The conventional style idles better and runs-out fine too.

so the conventional style(with the hook) is the better plug?
