Denny - I think Joe may have called it. The coil fixed the backfire. Now lets talk about the hesitation.
Does it hesitate EVERY time you accelerate?
If not, just off-idle, at 1000 RPM, 1500 RPM, 2000 RPM, etc.?
Do you still have the W-1 one the engine?
If so, did you check the wear areas between the throttle arm and pump? These are the round hole in the throttle bracket arm may become elongated (replace bracket)? The rod connecting the throttle arm bracket may be grooved (replace rod)? And the same two issues at the top end of the rod.
There should be miminal play from movement of the arm to movement of the pump.
But also check the distributer plates as posted by crenwedge.
Jon.
