Title: Weber 36DR5

A little additional information on the Weber. It probably repeats what users already have, but confirmation is always useful.

I worked it out and the cost of the carb in 1950 was about £526 of today's £

These carbs are currently changing hands for about £2000 , not a bad investment , so if you have any on the shelf ......

Stuart,

It looks as you have posted a page of a book which contains data from carburetors. I wonder if this book contains data on a WEBER 30 DO as fitted to the Augusta. If so, I'd very much appreciate if you could post the page.  Thanks very much.

Would also be interested in any info on Weber 30 DO , I've actually found a 36 DR in the shed today, I remember my dad said it came with the Astura and a manifold to adapt it onto the Astura engine , could never understand why you would want to go from a twin choke to a single choke but was clearly an option

I have two pages on 30 DO, but I am having difficulty downloading them to the forum. If they do not come out with this message, I will try again ... no problem last time!

One of my difficulties of understanding what and where everything is on early Weber single choke carbs is trying to think in three languages one of which I don’t speak (Italian) and another I barely understand (German).

So far, we have a source giving names of adjustable parts in Italian, another giving them in German and a translation of some from German to English which does not use names generally used in UK. It is probably a very beneficial brain exercise for an ageing brain.

Does anyone have access to tuning information in English for early single choke Webers (or double choke which would also give names an English mechanic would understand). Some Alfa-Romeos and some Lancias which used them were imported into UK so one would expect information or even helpful schematics to have existed once upon a time.

Just out of interest, who in UK imported and sold Webers in the fifties? And who exactly is the company in Italy who made new 32DR carbs at a price far beyond my pocket? Presumably they were still able to find or else they made jets, etcetera.

Here are some pages from a 1957 Motor Manuals volume dealing with carburettors which give some general principals.

I bought one of these from Cavallito in 1971 on an early Torino club trip for not very much money and some years later sold it to Gerald Batt for not much more.   Instead I have fitted the twin carb kit that i bought at the same time (??? I cannot wuite remember where it came from!).
