IGNITION  CHAMBER  AND  PLUG  MOUNT  DETAIL
Inverting the engine allows the plug mount and its relationship to the intake tube to be clearly
seen. During starting, the forced draft of fuel/air mixture will cross the tube and flow forward
down the side around the end of the spark plug. The plug mount is sufficiently thick that only the
spark electrodes of this long-reach plug are allowed to clutter the inside wall of the tube.
