The Perfect Corvair Carburetor
Dec 12, 2011 update to the Chevrolet Corvair Monza Spyder project car
With our Shelby project about done, we are turning our attention back to our Corvair and finishing up some details. In an earlier update, we changed the stock carburetor to a Weber DCOE 40.
We then sent the carburetor to Warren Leveque, a long time Corvair racer and tuner. He has experience in splitting the Weber carb so one barrel acts as a primary and the other as a secondary. This change helps deliver fuel more progressively to the turbocharged engine.
The jetting was close, but still not right. There was a definite dead spot, just off throttle, when you were moving from the idle and progression jet to the main jet. We switched to a F16 emulsion tube and also to a larger main jet, bumping up from a 130 main to a 150. These changes really woke the car up and eliminated the dead spot completely.
