34 PICT 3 re-build advice please....

[syncro]

Listed as electromagnetic cut off valve….
Pretty sure that’s air cut off…….I’ve read elsewhere where folks clip the plunger off the end but keep it installed. 
From The Samba:
"The 34-Pict carbs do not have an electric cutoff attached to the pilot jet, as some earlier models did. Instead, it has a cutoff valve on the other side in the idle air bypass channel. It is essential for the car to start and idle that the valve is opened, as normally happens when it's energized by the ignition
circuit. 
If you put an appropriate plug/seal where the cutoff valve normally goes, the car would probably operate normally, but may tend to run-on in some
circumstances."

The solenoid shuts off the fuel to the idle circuit.
