[QUOTE="greg brillus, post: 97120, member: 597"] Most auto advance units usually had two springs of differing tensions. The fact that these seem to advance quickly to me would suggest that at low engine speed pulling up a hill with too much advance would cause detonation. But the extra heat from detonation is very different from a retarded ignition where the flame is burning too late. [/QUOTE]
