1980 California
I have a 1980 California spec car with a Rochester E4ME carb in the UK. I have had a real problem with it later after I had to put in E10 petrol. I got a rebuild kit for it and changed all the seals, replaced all the |E10 with E5 and it now appears to run OK apart from the idle.
I have a few questions, in the picture above it shows a very small bore vacuum pipe (circled), that is sucking, but i am not sure where it goes. There is also an earth strap (square) that I can see but does not obvioulsy connect to anything. There are also 2 resitors/capaciors (not sure) that don't appear to do anything and also one appears to be broken? Any ideas?
I am also after a dwell meter to test the Solenoid switch on the carb and also the distributor dwell angle, what is the best one (as cheap as possible) that I could get in the UK and use to check?
Any help would be gratefully received.

I have looked on line at meters but they only seem to show the Corvette from 1981. They say the ALDL connector is under the ash tray but it isn't.
Did the California version have the "Computer Command Control" system with the ALDL interfaces to the Engine Control Module (ECM)

I believe that ground strap was permanently attached to the plastic distributor cover as mentioned,is the cover with the car? The vacuum hose shouldn't be too difficult to find where it goes,that might be why the car won't idle.

No the distributor is as shown in the picture. The earth strap is connected to the same bolt as the two resistors/capacitors. I'm not really sure what the vacuum tube is supposed to be connected to or what purpose it serves.

The copper ground strap was originally attached under the valve cover screw at one end and the black plastic distributor cover at the other end. It was held on by a wingnut. The cover is used to prevent electrical interference with the radio AM reception.
