I'm not sure how to change the timing. I didn't adjust any linkage of anything. Is this where timing is adjusted, in pic? This is the first outboard motor I've ever worked on, so I'm kinda clueless with some things. I've rebuilt Chevy 350 motors, motorcycle motors, small engines for lawn mowers and such, but these outboard motors are a completely different animal.
They sure are , I dont know your motor but basically two stroke outboards at idle spark timing is at or even after tdc ,1st (roughly 1st ¼ ) part of throttle lever movement only advances spark ,then from ¼ to ¾ throttle lever movement there is a bit more spark advance and the throttle butterfly in carb goes wide open ,and then from ¾ throttle lever movement to full speed the ignition goes to full advance. There is no auto advance ....and if you slam the lever right down quickly the spark will go full advance while motor is still at idle speed .........so yeah , a whole different animal .
Throttle lever linkage is connected to the ignition timing plate under flywheel and rotates this plate to advance or retard timing and ( on my motor ) there is a cam on the timing plate that acts on the carb butterfly to open them . The carb butterfly is not directly connected to the throttle lever . Idle speed is generally set by adjusting the spark timing . Setting this carb -idle-timing thing is known as "link and sync " and you need to get this adjustment right for things to work as they should . I would get a workshop manual ( probly a pdf on line ) .
I gotta say that when I 1st saw such a set up ....after dealing with cars, bikes and chainsaws I couldnt believe what I was looking at ....seems real half arsed but it works well .
A manual is the best money you could spend on your motor
