Best carburetor ever !!!!
Thought that is was a lemon and then relized that I didn’t have the distributor advanced vacuum hooked up , and it is the best carburetor I have every had, works flawlessly you can let it set for 5 hours and come back and turn the switch and it’ll crank up with out idling down one bit !!!!!!!!!

Works for me starts right up on my 1980 Monte Carlo 327
The media could not be loaded. It’s a solid carb for anyone doing a period-correct build or just wanting reliable performance with a vintage vibe. Not flashy—just works.
