You should have around 18/20 degrees initial timing.

Demon carbs like more initial timing than other carbs to work at their best.

A Carburetor is simply a device that mixes fuel with air and is dependant upon the flow of air and vacuum to work properly. If you have to put that much initial advance into your engine to make it work, it's because you are putting a band-aid on another problem.

The carb and it's function are not impacted in the slightest way by timing.

I would suggest that if running a lot of initial advance makes your engine run "right" that you take a look around for other problems such as vacuum leaks. Also you could also benefit from using a vacuum advance distribuitor with the vacuum advance unti connected to manifold vacuum. This will give you a much higher initial advance that is variable depending upon vacuum - thereby reducing the opportunity for detonation to cause irrepairable damage to the engine.
Having had a med-riser 427 that was severly damaged by running too much initial advance and no vacuum advance - I know that FE's are not impervious to the problem..
