Review on Holley 0-90670 Truck Avenger 670 CFM Model | Square Bore 4-Barrel Vacuum Secondary Electric Choke Carburetor by Mike Wachtel

Bolted right onto my Chevy 350 K5 Blazer and launched. When idling, the unit turned out to be a bit rich, but can be adjusted well with a vacuum gauge. Off-road mobility as described. I can't shut off the engine or flood when camber is off. My only complaint is the hesitation under quick acceleration. It turns off, then it goes up. I need to try an accelerator pump cam kit to alleviate this problem. Oh, and I hope MPG isn't the problem. In a standard truck, consumption does not exceed 8 mpg.
