Ok, to clear up the confusion.....I hope !!
This is the solenoid/ air cut-off on the Solex 34 PICT 3 , as installed on this bus:
....and this is the solenoid/ fuel cut-off on other Solex , this type
not on this bus:
I have learned that the function of the solenoid is carb. model specific and very different.

Thanks Les, very happy with the result....
I thought it worth a shot to try and re-build before it was replaced, turned out well........and a lot cheaper, with the added bonus of a lot of learning gained along the way.
A very worthwhile exercise.
Cheers,
Mark

Happy to be educated but I'm confused and tend to look for repeated references to the same thing for guidance....
From one pedant to another, ( and I mean that in a positive way ), why then is the part I'm using listed as an air cut off valve on the JK website and referred to as such in numerous articles...?
I know that the terminology blurs quite a bit depending on the article read....(particularly the individual jets).... but there is a consistency with this particular part.
Surely it would be in the seller's best interest to have the description correct....I wouldn't want to pay for a fuel cut off solenoid and be sent an air cut off solenoid.
Both are listed for the same year vehicle, but are Carb model dependent.
Heritage Parts also has its description as... " 12 volt carburettor air cut off valve. For 34 PICT-3 Carburettor "
and further down......................................... " IDLE AIR BY PASS CUT OFF VALVE FOR 34 PICT-3 CARB 12V "
Could it be that this part cuts off the mixture of air and fuel in the idle circuit ?
That would make sense to me
Cheers,
Mark

Since when do you believe the listings from JK or Heritage? They are both terrible. Heritage are the ones that I really hate dealing with. Arrogant bunch of halfwits.
