Re: was reading manual got a few ?s
It looks like you are missing an adapter plate as in this pic. Reroute your cable and fix the throttle cable action at the carb.
And your carb rust is simply from humidity and steel. hard to fight that except with paint, or anti-corrosion stuff like wd-40, oil or any number of products to seal out oxygen/water.
also like to add that you are smart to get this right. throttle and shifting control are critical for safe boat operation.
I noticed in you pictures you don't have a cable clamp on the motor, where you see mine has a clamping feature that is mounted to the motor and secures the cable so you get predictable action at the carb linkage. Then the adapter plate gets the force going the right direction.
This is all stock on my motor. different carbs, yes, but it seems like what your arrangement is missing.
good luck! oh and nice tarp, mine is green
