30 degrees at idle & 38 at 2000+ OK?
My 383 seems to like 36-38 total advance (I only have mechanical advance) but at idle it only drops to ~30 degrees. Is this OK? Idles great. How much total advance should Mechanical advance give you? I have tried different weights and springs but only get a total of 6-8 degrees above idle. Adding vaccume to this setup causes several problems and performance issues I would rather stay away from.
