The vacuum hose coming form the booster is hooked to the carb. I was told its not getting enough vacuum and it should run to the intake instead.
Did the individual who made this diagnosis measure the vacuum at the booster? Unless there's more to your story than you posted, only part of what you were told is true:
the power brake booster should be plumbed directly to intake manifold vacuum through a dedicated fitting and 11/32" thick-wall, reinforced vacuum hose that is specified for vacuum brake booster service. However, even routed to the carb, as long as the booster is connected to constant manifold vacuum through a 3/8" nipple (and the vacuum hose isn't collapsing or plugged or tee'd into the PCV valve hose), the booster should provide sufficient power assisted brake application for at least two brake pedal strokes. You stated it had
NO power assist, whatsoever. You also stated the engine labors at idle with extreme brake pedal application. Both symptoms typically indicate a leak in the booster diaphragm or faulty internal valving - hence, a bad booster.
Nevertheless, if you think vacuum hose routing is your problem, then reroute the hose. Ultimately, the repair strategy is your decision. We're just trying to give you a valid response based on what you've expressed.
