[QUOTE=HarryM;3232129]If the only thing you touched was the points, and the advance increased from 4 degrees to 30 degrees, then the points gap is too small. [QUOTE]

Actually, increasing the points gap advanced the firing point. For a given breaker cam lift, the opening point must come earlier for the gap to be larger, hence an earlier firing point. Large gap:advance. Small gap:retard.
