low intake vacuume reading
My 77 dodge powerwagon has a 360 with a holly 2bbl carb. When I hook up a vacuume guage it only reads about 14 to 15 hg. Why could this be? I replaced the intake gaskets and rebuilt the carb but it's the same.
On my trailduster with a 4bbl it reads over 18.
Any Ideas or is this just how the 2bbls are set up?
