I have a modified 71 that had FI but someone installed Carbs. 32  PDSITs. 
Now it runs, but runs rich. Further investigation and after reading  the 
entire debate on carbs vs FI, I now know that is should probably not have  an 
electric fuel pump as it is running very rich due to fuel making it past  the 
float valve. Plus, the driver side carb has the idle shut off solenoid,  but 
the passenger side does not. In fact, there is nothing but a  threadded 
hole. So, in order for me to go further on this, I need to source  one of these 
guys and wire it in or get two of what is #19 on the widely  available 
rebuild parts break down on theses carbs. 

Any one have  one laying around that they would be willing to part with? 
The idle shut off  valve. I am probably calling it the wrong name. In MG 
terms, it is the Anti  Run On Valve.


That valve, is called an idle control solenoid. It does exactly like  
you're thinking it does, meaning it retracts a plunger, and allows fuel to  flow 
thru the idle circuit. When the ignition is shut off, the plunger  extends, 
and fuel is shut off.

On both my 65 Notch, and my 64 T-34 Ghia, I have the screw in mechanical  
version of those electric valves (it's a brass jet with a ball bearing in 
it).  Most of the good VW parts suppliers stock both. I think Mike Fisher said 
he  even used a bug version on his 67 T-3, when he found 1 that was bad.

To find more info on Solex carbs, you'll probably have to buy a Blue  
Bentley, as that's about the only real source on them, that I know of. This  link 
might help as well, if you don't already have it.

It covers fine tuning them, but also assumes you already have a complete  
working set up.
