Carb. Mechanical or vacuum secondaries?

A properly tuned double pumper will deliver decent economy and blow the doors off the VS.

Im at a loss as to why people think you can’t tune a DP for performance and fuel efficiency.

It functions like every other carb out there.

yep. You drive off the front barrels, and they are set up just like a VS front barrels. I don't know why so many attach VS to fuel economy and DP for being race only.
