    A quick review of the attached link

    doesn't show a flywheel:


    Small, single cylinder lawnmowers engines use

    an Aluminum Woodruff key to secure a cast

    Aluminum flywheel, after incidents where the

    mower blade hit a big rock, or pipe stub protruding

    from the ground causing the cast Aluminum

    flywheel to shatter explosively.

    Checking a parts list for the engine should answer

    your question.
