Well first off the dlidfis set up is ok ,lots of coils . Did it run on the dlidfis set up before the carb was installed ?I did a 3 coil set up and it turned out one of my new coils took a shit (pertronics) so I switched to msd and it was all good from there.Did you check your fuel psi and is it going through a regulator at 4 to 4.5 psi ?Also is the fuel pump sucking through a straw or is it free flow (outlet on bottom of tank)? Is it a fuel return system or a dead head system? What fuel pump are you using?Last of all is the carb new or used?
