I have noted that for whatever reason,(seat angle?) demon metering blocks, idle mixture screw go fat after about 3/4 turn. Regardless of ifr or iab.

Holley,blp, quickfuel seem to be correct at around 1 1/2 turn.

I would say that this is normal for Demon carbs.



Thanks, and also to the others who said they noticed something similar.

This is the only Race Demon I've had the pleasure (?) of working with. On all the Holley stuff I've worked with I was always able to get all 4 fairly close to the same, maybe all within 1/8 turn or so, but this carb is not having it....so I guess I better forget some of the Holley experience if it doesn't really apply.

I like the idea of maybe closing the secondaries a bit/opening up the primaries to see if that has any effect on it. Have not tried that yet

Idle quality is acceptably decent and all the way it is, I was poking around to find ways to make it a little bit stronger. It's 451ci and the cam is a 262/264 @ .050 on 110 so I'm not expecting any miracles.
