What do you mean by flooding - is gas pouring out of the carb (shut engine off and see if the gas still flows out), or is the engine just bogging down - engine hesistation?
If this does this when only cold and improves when hot - may not be a carb issue. Could be a problem with the choke, bad fuel pressure regulator, clogged EVAP system (charcoal canister), clogged vent, etc.
Also what setup is this on your 22R - is it the single or dual 45 DCOE carbs. I assume the rebuild kit your changed the accelerator pumps and made sure to soak it enough to make sure everything was clean - all o-rings in place, needles are clean, new carb gasket, all vacuum lines in place, etc.
