Uh, I wouldn't call 12-14 on a 110 excellent results. Plus your surge at idle sounds like the car is running far too rich. I surmise the float level is set too high, or the needle valve is not able to hold back the gas when the car is only idling. i.e. the level in the bowl keeps increasing till it starts to spill out into the carb throat.
