Can anyone identify this Demon Carb? I cannot locate any numbers on the carb, and none of the info on their website helps me. It's running very rich and I have no idea how to know it's cfm or how to adjust. Thx in advance.

Looks like either a Road Demon or Road Demon Jr. No idea on size just from that picture.

Can't tell you for sure unless you post the #'s off the drivers side of the carb main body.

Here's a few more

Like I said, it's a Road Demon of some sort, no one can tell you size without the ID #'s...or measurements of throttle blade diameter and venturi diameter.

Just pictures is only going to get you so far in identifying it.

All adjustments are just like a Holley 4 barrel.

OK, I'm going to look for some identification numbers on the driver's side of the carb. Thx.

The rear boosters are annular. If the primaries are annular, it's a road demon jr. 525.
If the primaries are downleg boosters along with the rear annulars, it's a Road demon Jr. 625
It has to be one of the two as if I recall correctly the road demon jr. 725 had primary and secondary down leg boosters.

It's a road Demon Jr. as DV said. It's either a 625 (#6 w/dimple) or 725 (#7 w/dimple), due to the downleg primary booster along w/the straight leg secondary booster.

The size ID is also located on top of the carb , see the drawing below:

Thx for this information. I think I can figure out exactly what I have now!
