Vaccum pipes
Vaccum pipes
Hi there, I have a72 square that is just about ready for the road, I cannot find how to install the carb vaccum pipes. The left hand carb has 1 pipe below the carb, the right has 2 pipes below the carb. I have fitted a vaccum advance dizzy as the acuspark dizzy was no use. Also the left carb is not running correctly, thanks in advance for any help cheers Mawsy
Re: Vaccum pipes
Are you auto or manual? The manual will only have 1 vacuum pipe. It runs from the left hand carb to the vacuum unit on the distributor.
Could you be referring to the balance pipe which connects to the manifolds?

Re: Vaccum pipes
On the carb manifolds I have 1 pipe on the left carb, and 2 on the right hand manifold, I have plugged these off with tape

Re: Vaccum pipes
Ok they are the balance pipes not vacuum pipes. Either as my purples has posted. you have one manifold with the 2-1 adapter fitted and one with out. Or you have two different manifolds

Re: Vaccum pipes
It sounds like you have two different manifolds. I do have spares if you need one to match.
Balance plpes
Hi all, I have a72 square almost ready for the road. Problem is on the carb manifolds there are balance pipes, 2 on the driving side carb, 1 on the left hand carb of a smaller diameter. The carbs are solex pict 3, 32/34. How are these connected. I have a drawing of the balance pipe crossing the engine but no details of connections help please cheers Mawsy

Re: Balance plpes
That is brilliant cheers Mawsy
Re: Balance plpes
As i think we established in your last thread, you've got a pair of mismatched manifold sir.

Re: Balance plpes
How do you reach the conclusion they are mis matched
Re: Balance plpes
In your previous thread you said one manifold had two ports and the other had 1 port. They should either both have two ports, or both have 1 port.
As couple of us mention here viewtopic.php?f=26&t=13884
Ive moved this to the workshop and merged it with the original thread for you. Hopefully more people will see it here

Re: Vaccum pipes
Which do you suggest using, the manifold with single pipe or the one with 2 connections, I think the single for ease of connecting balance pipes cheers Mawsy
Re: Vaccum pipes
Im sure ill be correct if im wrong, but the single connection manifolds were for carburetor engines and the two port manifolds were for fuel injected.
So on this link https://volkswagen.7zap.com/en/rdw/typ+ ... 129-18000/
items 2 and 4 are fuel injected and 1 and 3 are carburetor.
A little aside, ive have been running items 1 and 3 with carbs for nearly 10 years and they dont cause any issues. I think all that matters if you have a matching pair and seal all the ports.
Hope this helps

Re: Vaccum pipes

Re: Vaccum pipes
Hi there Mawsy here,got photos of square for sale what email address do I use to post cheers Mawsy
Re: Vaccum pipes
You don't use an email address. You will need to join a website like flickr or imageshack. You upload the photos there, you then need the direct or img link. Then on here at the top of the reply box is a button with a little picture. Click that and you will get img in some brackets. Paste you link between the two imgs and your done. There are a number of guides on this forum too if you're stuck
