^ No fuel dripping from the boosters at idle.

Measured the valve lash, found intakes at .014" and exhaust at .018". I do not have a cam card that specs out the valve lash for this cam. Internet specs for valve lash are all over the place. So I opened up lash to .020" on both intake and exhaust.
Immediately on restart vacuum fell to 15"hg at 1100 rpm. Now able to idle down to 800 rpm at 10"hg vacuum.
