BUT with all my screwing around trying to figure it out I think I messed a few things up. The boat is running great, but I have the mixture screws all the way in. If I turn them out the RPM's go down. Maybe the float is too high? Any ideas appreciated.
Begin with them all the way in, turning each one out approx. 1 - 1-1/2 turn. That should get you very close. If that isn't feasible, you have another issue. Patience. The 4160s are cantankerous but once you learn the characteristics, they work just fine (for the most part).
Make sure the electric choke is adjusted properly. Typically, mid-range on the scale will get it very close. Powervalve can also trick you, so just make sure it's seated properly and is in good working condition.
