Help - identify carb part

Oct 19, 2007 4 Replies

I need help with my Weber 32 ADF carburetor (I am fitting it in my '87 BMW 316 - replacing original Pierburg 1B2).



I have Haynes manual for it (thanks Noel), but this bit is not described in it.



Here is the photo:

I think that it's power enrichment circuit, but I am not sure. I connected it to vacuum under the throttle plate (as can be seen on the photo).



What is your opinion, did I connect it correctly?



Yes. It's similar to the one on my 38DGAS.

I can confirm that it is some sort of power enrichment circuit, I tested it by applying vacuum, and when I disconnected the hose small amount of fuel was released.

the vacuum hose should not have any fuel in it, if it does then there is a fault, either a leaking diaphragm or it is misfitted.

As soon as I posted I realized that I have not finised my sentence properly :-)

It should be: "... and when I disconnected the hose (from the vacuum pump to the power enrichment valve), small amount of fuel was released to the primary carburetor barrel."
