I'd call Don over at FBO. He does a lot of work with demon carbs and he would be a good source to tell you what might be wrong or if its too much or too little carb

Fresh 440 build mild cam (488 lift)452 heads,headers,2600 stall,holly street domonator intake,mighty demon 800 cfm carb.cant get the idle circit right,at idle and warm runs rich and only opening butter flys up leans it out.do i have to much carb or is there something else?I checked vac and its 12in in park,power valve maybe?thanks
First thing to do is open up the demon and check for metal shaving and to make sure everything else is ok.
Then when adjusting the idle don't move the idle screw where the airclearer stud goes is a philips head screw in there use that to adjust the idle "idle ease" The throttle blades should be set to factory spec.
demon carbs are very sensative if your timing is not correct more so then other brands imo
Also according to Barry grant you are over carb my 750 speed demon flows around 920 cfm i would guess that your 800 mighty demon would be higher since you have no choke tower. This was confirmed thorugh BG and other board members that the demon carbs are underrated interms of cfm
