Thermoquad 1966 Metering Rods

Actually the thermoquad on my car now is a different carb. This carb has .98 primary jets and 2024 rods. Secondary jets are .137. Prevoius carb had .101 primary jets and 1966 rods. Secondary jets were .147. So carb was more responsive. Reason for change is this carb started to leak fuel. Needs kit. New carb I had already rebuilt on shelf. So probably need to change rods and jets like old carb. I also want to try colder spark plugs. Now have rn12yc going to try rn9yc range like 1969 340 specs.
