It runs much better on 220v

That is more a function of your installation. It is not a function of
120V vs 240V. If a gazillion amps were available at the terminals of
the motor, you would not be able to tell a scintilla of difference
between 120V and 240V. Inside, the motor can't tell, because the split
windings always see 120V. They're wired in series for 240V and in
parallel for 120V.

Do not adjust it unless its running.

Yeah, every time you see one in a store, there's a big sign telling
people not to do that. Is yours harder to turn coutner-clockwise?

The variable speed is obtained by using tapered pulleys that expand and
contract. When turning one direction (CW), you open the pulley inside (this
would be the easy direction). When turning the opposite direction(CCW), you
are attempting to close the pulley halves. If this is done at a stop, you
could break the internal pulley. This account for the difference in torque
required to change speeds.

It's called a Reeves drive.
