DG Pierburg oddity

[waltraud]

Hi,

I'm just about to fit a pierburg to my DG which presently has a solex....as it was a new engine fitted with old ancillaries in Germany....the pierburg which came off another dg but history unknown has been stripped, cleaned etc. I hav found a very odd thing though. The small ID black rubber pipe between the choke pull down vacuum unit and the vacuum intake at the base of the carb had something inside it restricting air flow in either direction. I pilled it out and it looks to me a bit like a tiny little carb jet with a tiny rubber ring around it. Effectively it was blocking the tube.....i thought ;oh it must be a one way valve...' which might be the case but looking at diagrams of pierburgs there is no indicatio of any valve or blockage in the pipe.......unless someone blocked off the choke? Worst case scenario is its something from inside the carb thats been dislodged and came out of the small vacuum fitting just below the solenoindful cut off valve......help?

Does this exploded diagram help any?

Cheers Covkid,

wonder if you ar anyone else can help on a couple more points. Just fitted a correct Dg single vac carb and Pierburg this afternoon and she starts fine and now to set up.but still wondering on a few points. There seems to be an alectricsal connection sticking out the side of the dizzy just behind the vac unit as if you should attach a female spade terminal and wire on there to somethign..? Is this a ground or to be ignored..seems unlikely to ignore it......The other thing was on the rear of the pierburg at the base there is one vac inle from the dizzy and another one which i think goes to the air filter asssembly inlet (if still there) so i could use it as intended or just block off? thanks. NB Do you know if df and dg had different accelerator cables as I now realkise that my accc cable was connected to a solex df set up which places the carb and associated bits nearer the centre and front of vehicloe, hence now won't reach. Thanks if you know.
