You are right – every avenue.
Capacitor is new as well!!
Distributor cap is the only thing what is not new (don't have it in spare). But a good point, will looking after one soon.
I checked the Valve adjustment as well, they are not to tight. But I must admit to my shame that I haven't done it very often. I checked the valves when they were closed and followed the Owner's Manual for Cyl. 1 and 4.
I installed a new set of plug wires this morning (not bunched together in the wire holder), haven't fire the engine yet (low battery).
The "unusually" is since I bought the car, it was never running quiet good. I haven't used the PA a lot (around 300miles after restoration), but this summer I will have him on the street as much as possible.
You are right 9PSI is low, i suspect to low. Manifold is checked for cracks. Not sure about the carb.
About your 29 - never touch a running system
Thanks Chet!!
PS: The reading I am using is BAR, I converting it to psi.
I added to my post "21 inch of mercury = 10.31 psi So 9 psi at idle may not be a problem if you are measuring in psi."
21 inch of mercury = 0.711 Bar
Sorry for all the trouble but it is a good problem to get the old brain working.
