Super Six install on 1974 Dart
Looking into the carburetor, it's not pretty. The mechanism that holds the metering rods should just lift out (right?) but it was frozen in place until I soaked it in PB.
Maybe even worse, the throttle plates were completely crusted with rust and the throttle shaft was completely frozen.
PB didn't free it up, even after several days of repeat applications. I did manage to free it by boiling the throttle plate in a solution of about 50/50 vinegar and water, but it was extra-strength "30%" vinegar. I added some Simple Green concentrate for good measure, and I put everything in a disposable aluminum turkey pan on the gas grill. After about 30 minutes of boiling, I was able to start working the throttle plate free with two pairs of pliers. After 45 minutes it was completely free and the rust was gone. I rinsed with baking soda and water to neutralize the acid.
I should have sprayed WD-40 or something to prevent the surface rust that formed within the hour. Next time...
