serious CARB question.

[beebster]

My truck ran great, so what do i do? I adjust the HEI,adjust the jets (mixture) and now when i get to 3rd gear it bogs out and dies.
It seems like it's flooding, so i replaced it with another q jet (they are both q jets) and the SAME thing! It bogs out and dies when it reaches third.
Got me pullin my hair out trying to figure it out.
I also noticed the wire to the HEI (Bat.) connector is just jammed in there, no proper connector.

any suggestions?

p. s . Its got an aftermarket (small) fuel filter in the fuel line from fuel pump to carb..
