Really bogging down in 3rd gear
I swear, some these posts are like the ring toss in a circus.
A giant table of possibilities and everyone throws their ring.
Just for the heck of it I toss mine at the "starving for fuel" bottle with Oldkimmer and see if I can land on top of his ring.
Still it could be a bad module, coil, plug/plugs, plug wires, timing, distributor, rotor, fuel, carb and a few select other things.
