10 degrees is correct for an 18G, GA, B, D or G giving 20 crankshaft
degrees. The vacuum capsule should be marked 5 - 13 - 10 meaning it starts
at 5 in Hg. stops at 13 in Hg. and has a max advance of 10 distributor
degrees, 20 crankshaft degrees.
15 degrees is correct for a North American 18GF, H, J or K up to 1971.
This equates to a max advance of 30 crankshaft degrees. Vacuum capsule as
above.
