Quote: There seems to be a pretty common theme to most of the replies here. The OP is asking about timing for a pump gas combo and almost everyone has replied with a racing engine likely running higher octane race gas. Higher octane (maybe too high) needs more timing due to the slower burn. The engine masters combo is a totally different animal so there's no need to compare that one.
You are the only one that fully understands why i asked this question.
