Are the ghetto carb plugs that bad? I looked at the car again today and it seems as though only the top two (trailing?) plugs are getting spark, and not the bottom two (leading?) Then when I switched the wires from the distributor to the coils the bottom plugs worked, but not the top... Could this be my problem? Would it run fine with the choke pulled on just leading or trailing, but not be able to hold idle with the choke off?
