Arrived faster than expected!

Good job Mess Depot for fast delivery! Installed and works great! All that was needed was an idle and choke adjustment. Pretty set up to run straight out of the box. Watching some Youtube reviews helped the process run flawlessly. There were a lot of fasteners in the box, but the nuts were the wrong threads for the bolts. There is no big problem. Supplied with plate and gaskets to accommodate reamed openings. A well thought out product so far.

Pros
  • Features: Runs: 4 | Boosters: Triple Stack | Brand: Demon | ft3/min: 625 | Throttle: electric | Condition: New | Output code: 3 | Finish: Glossy | Fuel: Gasoline | Fuel inlet: single | Marine: No.
Cons
  • So-so

NEW OR USED? in Carburetors & Parts

Arrived in poor condition. When the box was opened, the packaging containing the equipment was torn, and the equipment flowed into the box and into the carburetor. The carburetor had a few scratches and nicks and I was very upset that I bought a NEW carburetor that looked used. I was able to get the hardware out of the carburetor and continue to use it until the end of this project despite the poor condition. Started immediately after filling the carburettor and was fine except for a small idle

Demon Carburetor on Fuel System

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

Pros
  • All New Street Demon redefines the street carburettor with clean looks and ease of use! The Street Demon offers enthusiasts a simple carburetor designed for a stable idle, surprisingly crisp throttle response and smooth operation. Its optimized calibration and double mounting scheme make it ready for use on a wide variety of engines and vehicles.

  • There are nuances

Best Carburetor Period best in Carburetor and Parts

I was looking for something that would make my car run better. I have Holley 750 vs and EB 600 and 800 and no matter what I couldn't get my car to run properly. I was about to get started with the efi sniper when I came across this old demon video. Right out of the box I installed it in my car and I'm doing a burnout in first gear at 10mph on a roll. It's insane how responsive it is out of line and it absolutely kicks in when you push the pedal all the way down and now secondary filters engage.

Pros
  • NOTE: This carburetor model is in the form of square hole flange bolts. It can replace Holley, Edelbrock, Carter AFB and Autolite 5 3/16" x 5 5/8" carburetors. If you have an expansion port intake manifold, you will need an adapter to install this carburetor. Similar to Mr Gasket #1932.
Cons
  • Not the best
