My chevy 350 has been driving like its out of gas for the past week. At first it would get up to around 65 mph and start to sputter. Now it wont go faster than 15 mph. When doing some trouble shooting, i disconnected the vaccuum advance from the carburetor and there was no change in rpm at all...
Good day Gentlemen, do i have both manifold and ported vacuum in my distributor? Please take a look on the illustration below.
Below is the photo of the actual distributor.
