If I am understanding you correctly, you want a synchronous Weber, not a progressive? If so, the DGAS is a synchronous carb. It is probably cheaper than the ADL. A synchronous carb with same size venturis could be turned either way.Lasse H said:If it is normal Weber DGV(/DGAV/DGEV) 32/36 the secondary should open only mechanically as far as I know.
I guess most (if not all?) Webers use only mechanical linkage to open secondary. At least the popular(?) DGV, DGAS, DIR, ADF and DAT.
Btw. I'm planning to buy Weber ADL 38/38 (designed originally for Lancia Gamma 2.8l V6, I read somewhere) which opens barrels synchronously. I assume primary and secondary are in wrong order for CIH, but it shouldn't be big problem if I turn the carb 180 degreest. Right?
The blue book (Haynes Techbook 10240) is a little more up to date and has some stuff on SU's and Strombergs. I like it because it has some information on tuning jet sizes and emulsion tubes. I believe the venturis are i the same.Lasse H said:Are venturis of DGAS same size, what is their diameter?
In an ADL they are 24mm and 29mm. It seems like getting a (good) DGAS here is quite difficult, but I know one very little used ADL I could get quite cheap.
My Weber book is the blue one, but I've also seen that green one once. Is there any big differences? The green one lacks of the "how to install dual Webers into a VW Beetle" section at least. (Very important. )
