Abstract
An engine including an engine block, and spark timing structure for advancing and retarding spark timing between a minimum spark advance and a maximum spark advance, the spark timing structure including a spark timing link comprising a stop and being movable between a minimum advance position and a maximum advance position spaced in one direction from the minimum advance position, the spark timing structure also including a spark timing lever including a surface and being movable between a first position wherein the surface is spaced from the stop when the link is in the minimum advance position, a second position wherein the surface engages the stop when the link is in the minimum advance position so as to provide common movement of the link and the spark timing lever in response to further movement of the lever in the one direction, and a third position wherein the link is in the maximum advance position when the surface engages the stop.
