I'm not one to knock the competition, but if you paid someone to fix the motor, I'd take it back to them.
Those motors are pretty simple. I've got a 1985 that I bought new and except for wrecks, sinkings, etc. it still runs like a scalded dog.
That being said, I'd check to see if the fuel filter in the tank was stopped up. Assuming you have the old style fitting with the ball in the end of it, stick a stick in there and squeeze the bulb. Fuel should squirt out. Make sure you have fuel bulb pointing the right direction.
If you have access to another tank, try it.
I can't remember how those old fuel pumps work. I've never had to fix one, but anything is possible. Log on to one of outboard repair boards. The info is there.
