Just to bring up a possible misunderstanding by all...maybe it's me. Does the actual vacuum at idle pull the spring loaded advance back, and then with the lack of vacuum at acceleration release the spring loaded advance to actually advance the timing? Then as vacuum is regained as rpms increase, pull the spring back until another loss of vacuum pressure is realised? I know it's kinda a which came first the chicken or egg question. Any thoughts?
