normal engine vacuum
What should my manifold vacuum be on a 79' sc? I am getting 7-8", this seems very low to me. I believe I have a significant leak, though my idle still slows when the oil fill cap is removed.
Thanks as always! |

15" I understand is typical. Stands to hold on any regular gasoline Ic engine
