Bernie, the folks at BG will be the first to tell you that their carbs like lots of advance. I took delivery of my stroker with the Mighty Demon installed from the beginning. It seemed to be a bit rich so we reduced the jet sized on both primary and secondaries. It always seemed to run well (no hesitations, great idle, lots of power at WOT etc.) I finally took here in to a dyno tune shop where an additional 6 degrees if advance was added and the jets were returned to the values installed from the factory. Since the carbs are configured per the specifics of your engine and flow tested prior to shipment, they seem to get it pretty well "spot on" out of the box. Might need a little bit of distributor-twisting to get it all set up. Several of the local guys have yanked their Holleys and replaced them with Demon carbs. BG has a good name around here.
