Originally I was asking has anyone experienced fouled plugs when retarding timing too much. It seems the discussions have prompted many questions in an effort to help me. Please continue to ask for more info if necessary, I feel I have good knowledge of the topic and my set-up.

The whole point of tuning a car is to get AS MUCH TIMING AS POSSIBLE in the engine without causing preignition. Never have I tuned to retard timing. So I assume that you want to retard timing to reduce idle rpms??? I know your original question was about fouling plugs.... but you're not giving enough info to get right to the heart of the matter. I would ASSume the fouled plugs are a result of not lighting off the fuel mix or allowing enough time to light and fully burn the mixture. But it could be a couple of issues.
