Yeah, I have an AS manifold, but the vaccume problem here is in the orfice in the carb itself, with the smaller bore on the vaccume there is some hesitation before it'll actuate the vaccume advance for the distributor. Not as bad as I've heard that the 009 is with a 34 pict 3, but annoying.
I am still interested in GK's duals if bugnut cannot help him.
Thanks,
KC
