Quote: If his car likes 30 degrees at idle, changing his initial timing to 30 degrees and swapping the vacuum port may not work when he is trying to start his car with that much initial timing. With the manifold vacuum, his car will crank with only 12-18 degrees of initial timing which is better on his starter, especially in hot weather.
That's why I leave the slots long and use real light springs easy starting and nice idle advance!
