Poor Running When Cold and New MPG calculation 120-130

I've only checked the cam in that I made sure that all valves were opening and closing when I was cranking. I did not measure it as I was just confirming that my valves were all working.

I dunno about the carbs. This is my best set. 1968 HS6 with helical springs.
These are the originals to a car that sat unused for over twenty years, so aside form the frozen parts, I have a set with half the wear of most SUs.

That being said, t throttle shafts are slightly worn and I've got some plastic washers on there to keep out the potential vacuum leak. Otherwise, they perform quite well under most circumstances, I'd think I'd see some problems when it was cool, but not freezing as well. but I would like to have some teflon bushings installed with new throttle shafts. Sadly I can't afford to ship them to Rhys right now.

My other HS6s are terrible and very worn and aside from them, I have a pair of rebuilt (but still troublesome) HIF6s and a pair of unknown-function/condition Stromberg CD-175s.
