Picked up a used 750 Mighty Demon... where to start?

Just going off the Summit page it says 75/83 jets, 6.5" primary power valve and the secondary PV plugged. Will check tomorrow if the secondary plug was replaced I'm going to get a rebuild kit with new power valves anyway.

I understand the jets are rated above those of Holleys, also the carbs are underrated I read somewhere mine flows similar to an 830 Holley. I also understand basic carb principles where too big of a carb will run LEAN not rich so my first move after I test the carb as-is on my engine will probably be to jet up and/or get bigger acc. pump squirters... right? lol
