E85 Carb Winter Storage Question

So, for this race year I switched over the one small block race engine to E85 and bought an E85 carb. Didn't do a carb conversion kit. Car ran great no complaints! I read that it's a good idea to run the car for a few minutes on regular pump gas at idle before storing the car for winter. What I can't find is what carb adjustments do I need to run 93 gas in an E85 carb? I would think that since the E85 carb is setup to dump more fuel in the engine I can't just put regular gas in the fuel cell without flooding the engine? Also, doesn't E85 carb use different floats cause I know E85 is slightly heavier.

Thanks in Advance!!
