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

This Carburetor worked as advertised right out of the box. It clicked into place and everything fitted perfectly. The only adjustment required was lowering the nozzles one notch due to the altitude I live at (over 2000 feet). I've experienced engine RPM drops in the past only when going over the speed limit. Now I can ride it on the roughest terrain without the slightest jolt of the engine. The carburetor is expensive, but it pays to be calm in the knowledge that the engine won't stall just because the terrain is a bit rough.
