Duane, whose needle and seat do you use? ... I'd love to be able to run both ,but always had problems with the aux flooding. ....I also use the big line to the carb...... BG reg and pump.........Probably i'm being cautious too, since the AMC factory rebuild kits did away with the aux inlet back in the late ' 70's.....Planning to take the car to the Dutch Classic, I'll have to try running the aux, if the air is good it'll need all the fuel it can get.. ..... .Tom
