This will tqake a little experimenting but this will put you pretty close: 14-16 Degrees at about 1200-1300 RPM. Use a blue bushing in the distributor with 1 light blue spring and 1 light silver spring. Set max advance to 36 degrees (check at 2800 RPM). Use premium fuel and BF32 (Autolite) or the equvalent. Reset idle. The Webers will tone down a large part the of radical idle you previously encountered with a large 4bbl.
