I know that you want a simple answer but, have you done any troble shooting steps at the pump its self? when the relay is in does it pump at all? what is your lin pressure?

(1) You will need to adjust the float pin to get the correct amount of fuel in the float chamber of the carburator.
(2) You will also need to set the air-mixture screw , but before you do tht remove the spark plug and see whats the condition of it, is it black , is it brownish, or is it whitish.
If its blackish = means rich too much of fuel, if its browinsh= ok, if its whitish = its too lean.
(3) As for hesitation, check the needle at carbs piston on the accelerator cable, and blow the main jet with high pressure.
(4) Check too the spark plug gap and if its as per the manufacturers specs.
Hope this helps!
SOURCE: not getting enough gas to the carb have to run choke 3/4 engaged
Sounds like a restriction in your carb, not getting enough gas. I would clean out the carb again.
SOURCE: Will not run without choke
have you checked for vaccuum leaks at the intake manifold? you can check by pouring water over the gasket area when/ if you get it running!
SOURCE: Won't idle without choke
The pilot jet controls the air/gas fuel mix at idle . If the jet gets plugged up not enough gas gets to the emgine at idle. You will need to remove the carbs and float bowls and clean them, paying special attention to the pilot valve. Count the number of turns to remove the pilot screw and replace the same number of turns then turn counter clockwise 1/2 turn.
