88 indy 500 backfireing

not sure someone else did the carbs for me. when running if pull off the passenger side plug still runs but if leave that one on and pull the driverside it dies right out. when both plugs out driverside seems to spark proper and passenger side doesn't seen to be as good...

Welcome aboard! CDI's are good or bad, period, so it's not that.
