distributer for dual carbs

Do I need a mechanical advance distributer to use with dual carbs (webers IDF) or can I use the stock one?

Also, as per my other post: are manifolds for my 36 IDFs meant to be mirror image, as the ones I have are identical, ie not left/right handed.

I think the same for the manifolds ( well on 40's& 44's it is) not mirror. but some have a small pipe to equalize them which goes to the front on both.

If you have a rare Vacuum advance distributor, I would just connect it to one of the carburetors...
The vacuum advance ditributor will advance much quicker than the 009 mechanical distributor, as the it works on revs, centifugal advance... whereas the vacuum works straight away, NOT dependant on the engine revs at all...

PS: the Vacuum distributor is actually Vacuum/centrifugal...
so it Has to be better - faster...

I agree with 68AutoBug A Vacuum advance is good that said I was running a 009 on my type3 fastie (at the time only dissy in parts bin )with twin carbs and had no problems with it,

Hey Lee, is this right ?? I have a vacuum dizzy and I was gunna take it out to put in a 009.....lol:thumb plus is it rare you wanna buy one :P

( thanks for the tip)

Yes,No.Im thinking that you need offset manifolds for your linkages to line u.😉

Actually a vacuum dissy is just vacuum.:kiss

Get a 009

It just makes life easier. You CAN fit a vacuum dizzy, but i dont know anyone who has.

You dont have a balance line on IDFs. The balance line is a dual single barrel thing (Kads)

Manifolds

There is offset style and straight.
The offset style helps keep the linkage straight cause 1 and 2 cylinders are closer to the rear than 3 and 4 - think about it. One is not directly opposite 3.
When you fit then - but your carb on the manifold and just trial them and see if it makes a difference. Fit them what ever way makes the linkage the most perpendicular to the car - you get the drift.

Thankyou Blue74l, it all makes sense now, when I think about it, after your explanation.
