Confused

I was recently given a 1977 Oldsmobile omega (20,000 miles). It sat for 20 years, and I have done basic work to get it running.

Fuel pump, fuel filter, carb rebuild, water pump, alternator, fuel tank, plugs, radiator, etc.

It is fully stock, has a 2 barrel carburetor, and runs well, but  has a hesitation when accelerating from idle, and when it shifts from 1st to 2nd gear.  The only two thing I am aware of that is missing is the carburetor pre-heat tube from the manifold to the snorkel on the air cleaner intake and the thermostat. Also, it appears to gets pretty  poor mileage.

Any ideas on what might be causing the issue ?
