I tried that and the hole is too small. I think I saw somewhere that that hole was for cruise control.

Is that the original carb? If not that could be a manual carb or from who knows what.

Four barrel carbs get better gas mileage than 2 barrel? That seems a bit counter intuitive to me haha.
Two barrel carbs have large throttle bore and venturis to feed the engine throughout the rpm range, a four barrel has small primaries for cruise and secondaries for power, smaller the throttle bore and venturis the better the mileage that's why a four barrel is easier on gas, also why a Q-Jet with the tiny primaries gets better mileage than other carbs.
