71 Dart / 5.9 Magnum / Procharger

I would blow it apart and clean every port. Probably trash/varnish from the new gas. i built my blowthru carb and It definitely has bigger needle and seat. I will have to look thru my notes to get the exact size.
Took your advice, pulled the carb off the car and completely apart. Used a can of carb cleaner and air compressor to clean it. Went for a drive last night and everything is good now. Thanks! Hopefully we'll see a 1/4 mile pass soon on 10 lbs of boost. I've got a new carb hat that will point straight forward, just need to fab up a new charge pipe. Hoping for a 10 second pass very soon. Drag week is sneaking up on me.
