I got my 67 running recently after it sat for about 10 years without being started. New gas tank, cleaned fuel lines, cleaned carb and it runs fine until I try to drive it. It sounded like it was idling too high, and when I hit the brakes to slow down it would stall (i6, 200, automatic). I messed with the carb and now it sounds like it idles fine, and it doesn't stall when slowing down, but it stalls when I hit the gas unless I ease on the gas ever so gently. However, once it is moving I can hit the gas and it goes with no problem. Any ideas of what I need to fix? A friend suggested a vacuum hose, but I'm not so sure.
