Good afternoon.
It could be fuel related whether a fuel pump or carburetor accelerator pump. It could be ignition timing as well. You need a timing light to verify the timing. The EGR valve could be partially open causing a vacuum leak and causing the hesitation as well. These guides can help us fix it.
