You dont want it burbuling rich, I usually tune my low end to the point where its just lean enough to snap off a dead dig, I like to start from a rich setting and continue leaning it untill I get to that snapping response then its done, remember to get your high end tuned first, and keep the low end rich untill you are finished breaking it in. My method gives the total run time of break in about an hour or more.
