There was yet another reply by me to this thread last night. Not sure where it went.
The picture there now is one single cylinder snap'd from an overlay of all of them (the effect of the camera on the CRT).
I figured out which book I was looking for, namely the benz technical training manual a friend gave me way back when. It has dozens of sample traces.
The first thing that stands out about that first trace, is that it's upside down. The coil was installed by the PO backwards. I should have noticed that already. I clearly was more interested in playing with the carbs than I was with getting the car in good working order.
The other thing to note in the picture, once that's corrected (please see shot that was in previous & missing post
). Is that lead in section of the pulse has too much of a down-slope. I think that means it's time to clean the plugs and replace the old wires. A more concrete answer than that would be what I'm fishing for.
My goal is to do this though "logical and thoughout" processes, rather than knee-jerk replace the parts 'cause g-d knows when it was done last.
Thanks all.
