Distributor vacuum advance
Hi. I'm new to the forum. Just bought a 1966 impala, 283 2 BL carb, power glide trans. There's only one port on the carb and its full manifold vacuum with a line going to the vacuum advance on the dist. Doesn't seem right. When I unplug the line at the dist. and plug it to set the timing, its OK. After setting the timing and reattaching the line to the dist., of course the RPMs climb because the timing is now advanced. The carb was rebuilt somewhere in canada. Is this port on the carb supposed to have full manifold vacuum? Its above the throttle plates.
