Agree with Jim but want to adjust his post slightly:

The 65 base uses a smaller throttle blade size vs the 66.

The carburetor venturi (which sets the air flow of the carb) was the same or larger on the 65 carb vs the 66 carb. The air horn on the 66 carb (larger) made a slight difference in flow which probably offset the difference in the carbs too.
