Try cleaning the air bleeds with some carb. cleaner, by sticking the red nozzle into the air bleeds. This carb. worked well once upon a time. Also a blown power vale will cause ir to be rich at idle.

I would first warm engine to operating temp set floats, and then set timing. I would run as much intial timing as possible at least 14 degrees with full advance around 35 to 36. Then set idel mixtures to max vac or rpm usually 3/4 turn out. should idel about 950 out of gear. put boat in water and install vac gauge. make sure when ideling in gear u do not drop vac under your power valve vac rating which is usually a 6.5 vac rating. If you are below that you need to change powervalve to lower vac opening then in gear idel vac. Just my 2 cents good luck!

Just a thought but my carbs were set up by Dean at Nickerson's and have always worked perfectly till I got my first tank of fuel with alcohol then they idled just as you stated all the carbs needed a extra 1/4 turn at each corner in the idle circuit. then they were back to there normal idle
