First question, when running at idle is the vacuum line at the dizzy suppose to be zero? I disconnected the vacuum line at the dizzy and hooked up my vacuum gauge and and at 475 RPM idle it reads zero.
When I reconnect that vacuum line what would be a good reading range as I increase the speed of the engine. I'll probably have to put a "T" connection in the line in order to get a any readings.
I can't seem to find any written ratings in my shop manual for this vacuum line.
