Sounds like lean mixture.
Look for vacuum leaks.

Is the timing right?

I agree with MNS Kombi
this is usually a timing /distributor guts issue, the carbies are the last thing that should be touched unless something is visually obvious
Please, I need drivers side window regulator (winder mechanism) for my '54

Dont know much about Type 3's but in a Kombi there is a balance tube between the carbs, sometimes the rubber elbow's come off the pipe creating a vacumm leak, the symtoms are the same as you mentioned. might be worth a look if there is a similar balance tube in your car it could be the problem.

That might help a heck of a lot! Without the balance tube the poor little 34picts will be suffering badly from the reversion pulses.

Could it be a bad tension lead?
