    Two cylinder or three cylinder?

    Two cylinder call for Champion QL77JC4, QL82C, or L78V. NGK equivalents would be BZ7HS-10, BR7HS, or BUHW-2.

    Three cylinder motors use QL86C or BR6HS plugs.

    NGK plug numbers with a -10 suffix means the plug has been gapped at the factory to 1mm, or .040″.
