stupid questain;
is there a vacumn line attached to the booster? 
is that hose attached to the intake or the carb base?
Is the valve/connector in the booster working/not stuck closed
I have tried with it connected to the intake, also have tried with it connected to the 3/8 barb off the back of the carb....
No difference, I get 13" of vacuum in park and 11" idling in gear....but driving down the road the vacuum is up plenty for the booster.
What is the valve connector in the booster sucked close? I gotta look into this
'stuck closed'
The connector/fitting on the booster where the hose is attached usually has a valve in there. To keep the vaumn in the booster instead of it bleeding off right away when the manifold vacumn drops off during acceleration. Ya know, just in case you have to stab the brakes on a panic stop when somebody pulls out in front of you.
If it's rusted stuck closed the 'power' won't work as the vacumn can't get to the booster. Or it lessens the vacumn boost. Take it off, look inside, and rattle it. Some people will blow and suck on the valve to see if it opens and closes easy.
Also check for a leak around that seal.
