how and were do I change the timing on a 1985 kawaskai bayou 185 and what should it be set at?

 

Hey Bud---dont really know fer sure, but I would take a guess you could put an offset degree key in your flywheel---lots of posts on this forum about it---It usually advances your timing 4-6 degrees--doesnt make it a rocket ship, but seemed to help me in the midrange

 

how should all the markings be lined up??
