Review on 🚗 Holley Street Demon Carburetor: 625 CFM, Aluminum & Black Composite Fuel Bowl, Electric Choke, Gasoline Only, Vacuum Secondaries by Jon Brazil

So far everything works fine. I thought it should have been preset but the high idle was set too high. Make sure you check this before installing. Setting that up was great too. I've always had Holley carbs and they've always worked great, but I was talked into buying Edelbrock by a friend who swore I wouldn't go back to Holley once I had one. Well, that demon just replaced that Edelbrock. I will not buy another Edelbrock. The Edelbrock worked, but I couldn't start it cold or hot without having to pump the accelerator a few times and hold it slightly open, and that's not user error. I'm an auto mechanic and in the aviation industry I also have a few friends who own speed shops. This Holley Demon, cold or hot, I hit the accelerator once and it lights up instantly. In fact, it starts without pressing the gas pedal and it works amazingly. I will buy more for my daughters c10.
