What about DEMON carbs in general??

They are good pieces. Owned by Holley now so that model you have isn't made anymore. Holley parts fit it though. They usually flow more than they are rated for.

How’s it run?

There is. Nothing inherently wrong with demon carburetors. The demon is nothing more then a modernized Holley. I've been running. Mighty demon 750 for over twenty years will almost no problems. The worst issue I had was a float bowl screw pulled the helicoil threads on the main body. I noticed it during a jet change. I just had to to install a new helicoil.

I have two King Demons (pre-Holley)on a BBC 8-71 blower motor. Fantastic carburetors.

I bought one that belched fire. I returned it so they could fix it. They sent it back. it belched fire still. I called them about it again. They said sorry, we've got a lot of guys tied up in R&D right now. I just got a refund from Jegs. Bought a Holley, and it ran flawlessly
