Hesitation during acceleration wold be caused by the acceleration pump not working correctly.
Start engiine and run till the auto chole opens fully.
Remove the air cleaner.
Slowly open the throttle and watch if the accelerating pump is spraying correctly. If not, the pump requires serviceing/repair.
If the problem occurs at high speed and tends to bog down, check the fuel level from the sight glass.
Rev the engine trying to use as much gas as possible and note if the level drops drastically, if yes, the mini filter above the float needle valve is clogged.
If it is not fuel related, check the distributor cap, wires, ( especially the coil wire) and rotors.
