The difference was immediately noticeable. The car starts in 3 seconds vs 10 seconds. Engine running smoother, car feels quicker too. No adjustments to new carb yet. I'll fine tune with vacuum gauge in a few days. The original carb will go with the car one day.
Doesn't surprise me. I don't think that carb has ever been apart. Did you leave the '72 intake on it?
