I'd square up the t-slot first, then turn your mixture screws out 1.5. Then start messing with the idle bleed. Some of the newer carbs have an extra idle air bleed under the air cleaner stud, takes the fun out of drilling your throttle plates with small holes. If you have a pipe cleaner tool with a bunch of wire gauges in it, you can hang those in the idle jets and take a reading, then mic the wire and bleed id and just do the math for what smaller bleed you need. Does Weber still make the "power plate"?
