If it is secondary ignition (coil, wires, or plugs) it would likely do it under load (low RPM, hard pull) … [if you think it is the fuel system]…you might try loosening the gas cap (weird little check valve problem). Also, have you tried pulling out the choke a bit when it's doing it? If it goes away or gets better, it's fuel related. “
If you think it to be on the ignition side, start with the spark plugs. Advanced Discount Auto Parts, about a buck sixty apiece. Put em in and rule out those first. As all you have left on that side are the coils and the ignitor. (an ignition pickup coil too).
