[Healeys] Weber manifold related queries

[Simon Lachlan]

Hi,

It might not have escaped your collective attention that I'm in the throes
of installing 3 Webers in my 3000. I have yet more questions........

 

1)      I note that my MKII BT7 (tricarb) has a 3 way breather tube linking
its three, currently fitted, individual inlet manifolds. Furthermore, BMC
attached sufficient thought to this breather business as to actually
increase the size of said breather tube during MKII production. Yet the
manifolds which I've just purchased have no provision for a breather tube.
What do you think?

2)      My car has a factory fitted servo so I need a vacuum feed for that.
The manifold plug hole, pre-drilled in one (only) of the manifolds, is quite
small. How big a pipe does one need to keep the servo happy?

 

Thank you,

Simon
