Nice!! I added adjustable idle circuits to my outboards as well as a 4412 center. 500 ci motor though so it was a bit much for the factory calibrations.

Can we get more info on your process of adding idle circuits to the outboards and the effect it had on the idle adjustment/mixture settings?

Also, what does the 4412 change involve?

Thanks, any photos of the process would be nice too.
