A fuel compatible fiber washer may work better than a copper washer since you won't have to apply as much torque on the already compromised threads to get a good seal. Since you are dealing with tapered threads, your washer (copper or fiber washer) will need to be thin so that the tapered threads of the fitting will firmly engage with the tapered threads of the carb.
