You will get roughness due to the slow burns and ocassional misfires before
it quits no matter how well you match cylinder to cylinder air fuel.
There is considerable cycle to cycle variation in the burn rates and
effective power for a single cylinder when you get too lean.
BSFC also goes up around that point as well.
