Finally put a Crane adj. advance can on. I set the limiter plate to fully limit the amount of Vac Adv. (about 12 deg vac adv btwn 10-15 in. Vac). I spoke with Crane tech 2x, and although helpful, they did not seem very knowledgeble in the installation setting for the adj. can and limiter plate. Finally figured it out after a couple of hours.
