    Hi,
    A backfire generally leads one to suspect the timing (intake valve open when the spark plug fires) and thus I would suspect the flywheel key.

    The Flywheel is held in place by a short square piece of metal called a pin or key. If this key is missing, the flywheel though on the shaft will be able to twist on the shaft and thereby change the timing and cause the backfiring.

    Hi,
    Yes, it is behind the recoil starter; it is in fact the part that the recoil engages directly or indirectly. The ring gear attached to it is also what the electric starter engages. You will need tools necessary to remove the recoil, and then the flywheel.
    It seems to me that if you must ask these questions, then you have not the knowledge/skills or tools to accomplish the task.
    Peace,
