Is "Solex 32-34 PDSIT 2-3" an alias for "Solex 34 PDSIT 2-3" ?

I presume: Solex 34 was used on 74,73,72 T2s, while Solex 32-34 was used on earlier T2s.
May be I am all wrong: It's just two names for the same stuff. :oops:

32-34 is the size of the venturi it supports. 2 is the left carb, 3 is the right. The 32-34 stamping you are seeing seems to be one body used for two configs.

Type 3's used 32-PDSIT and 411/Bus used 34-PDSIT. The 32-PDSIT body is not the same as the 32-34-PDSIT body on the 72-74 bus carbs.

Thank you, to put me back on the right track.

I ask this because I want to get a set of used carbs to learn, rebuild and hopefully be ready when my 1974 dual carbs will need repair.

I want to make sure I get the same carbs I have presently.
The Haynes: 1700/1800/2000 1972 thru 1979 only tells about Solex PDSIT 34 2/3.

From your explanation, I understand that Haynes tells about a 32-34 PDSIT body equipped with 34 inners.
Are they 34 PDSIT bodies ?
You told me there are 32 PDSIT bodies not the same as 32-34 PDSIT bodies.

Ordering a Solex 32-34 PDSIT carb, I run the risk, it's equipped with 32 inners and be useless for me.
How can I avoid getting wrong parts ?
Is that easy to find 34 inners ?

The bus carb, stamped 32-34-PDSIT can have either a 32mm or 34mm venturi. It's removable.

The Type 3 32-PDSIT carb is not made from the same casting.

I think it's only the venturi that's different for european models. I think it would be hard to find one with the smaller venturi.

I forgot to say that my bus is a 1974 US Westy, that I bought in the US in 1977. It's likely it has 34 mm venturies.
( this Westy is now stored far away in France, and when I am there I have no Internet, Very inconvenient )

In the Haynes manual, dual carbs are named 34 PDSIT, there is nothing else.
From an old manual I have in French, I see engine CA august 1971 Solex 34 PDSIT 2/3 for 1700, Nowhere anything about 32-34 PDSIT, Nowhere anything about 32 PDSIT.

It seems, there is little chance to go wrong stuck with some 32 parts.

The manual will always say 34 because that is the actual carb model. 32-34 is only stamped on the part to save money by using a single mold.
