Sorry. Lost my train of thought.
Vacuum reading a nice steady 20 lbs at a very low idle.
No jumping up a lb or two like what a burnt valve would indicate.
In fact it behaves exactly like what a good. Onsition engine is supposed to: nice and steady 20 lbs.
Yea it's a slight "quiver" of the needle but stays uniform around that 20 lb mark.
Even through the "burble" or miss when it does happen.
In other words the vacuum gauge is not pointing me toward any suspect positive.
