Correct initial timing?

A properly tuned vacuum advance will make an engine so much more pleasant to drive and accelerate because the timing curve is more in tune what the engine really wants.
But ofcourse if you "don't care" for the beter MPG that might result of this, you can always easily compensate for that by pressing down the throttle more and often...


Myself I'm running at 10° BTDC initial, but the vacuum advance pulls it up to 24°, which is exactly where the engine makes most vacuum when idling in Drive.
