I suppose you have one of those carbs mounted in the center of a manifold.
 This problem is typical as this instalation does not have any heat at the
bottom of the manifold.  The gas from the carb just puddles at the manifold
bottom and pours(slugs) into the cylinders.  Not only does this create poor
performance and fuel economy, just think about emmisions.  The raw fuel also
gets into the crankcase as it washes past the rings.  Wait till warm weather
and things will be better. This is another one of those reasons the EPA is
looking to get our vehicles off the road.  We all nned to be more concious of
removing our FI systems for the cheaper way out.
