The 30 carb should work with the engine but won't be jetted correctly.
It might be something simple like the cut off value is jammed shut (it's below the throttle arm and has a wire connected to it.
You can check it works by touching a live 12v wire to it and listen for the clunk.
Sounds like your pict 28 does not have a cutoff value hence the extra wire.

 

30 PICT-3 has been used on the VW1200 since August 1970.
Generally the 12v versions for 1200 were '113 129 029' followed by a letter. If this is the part number it will be jetted correctly.

If it is any other number it could be a 1300 version
30 PICT-3 was also used on the VW1300 from August 1970.

28 PICT-1 was used on the VW1200 from August 1964 to Nov 1965

The wire should have 3 spade connections as follows on the 30 PICT-3:
Position 15 on ignition coil, to cut-off valve on carburettor(left-side) and then to choke on right-side of carb.
If you then turn the ignition on without the engine running, when you pull the spade off the cut-off valve you should hear it click.

 

Guys, you're stars!

Let me check when I'm next at the car, which probably won't be until next week as its at my parents place.

Cheers guys.

 

I got a 30 pict 3 on my '70's 1200 Bug. This runs fine except the worn mixture screw, but after research & reading through many threads on here and the Samba.com, it would seem that a slightly larger main jet would go amiss. I tried a 120 main jet - works well. The car is much better. If you look through the "Hot 1200" thread on here you'll get loads of extra help too. Alternatively you could try and get an old Weber W-222051 carb. This will also run on the 1200!!

 

Thanks Dazza. Maybe it's the jets that are shafted on mine. We took each of them out and blew down them but to the naked eye they looked fine. I've not had this problem before with a carb!

Does anyone know how to measure jets to see what I've got as there's no reason why I've actually got the right jets in the carb?

I'll have a look for one of those weber carbs you mention but would rather stick with a stock solex if possible?

Thanks all

 

Yeah the Webers are quite hard to get hold of. I got 1, and playing with it to go on mine.

 

I've got a 30 pict 3 on my 76 1200 and it runs great
i have had just over 80 out of it

 

I couldn't find the hot 1200 thread, but this one on here has some great info:

I just need to find out what jets I'm currently running, and will also check the cut-off valve.

cheers guys

 

i've got a 30 pict 1 on my 70's bug.

just saying that you dont NEED the RIGHT carb..... most will work to an extent

good luck

 

^ Thanks mate, I'll get my dad to take a look. cheers!
