Weber DGAS and DGMS carburetor parts.

The Weber DGAS and DGMS is a series of carburetors of twin downdraft design.

Each barrel has its own throttle valve on a separate throttle shaft.
However the throttle shafts are coupled through toothed cogwheels and consequently open and close simultaneously.

The difference between the DGAS and DGMS is in the choke (or cold start system) operation.
The DGAS has an Automatically operated system there where the DGMS has a Manually operated choke system.

In some cases, these carburettors are equipped with Weber's LoVE system which effectively means an anti-stall device activated through a vacuum diaphragm.
This Low Vacuum Enrichment is usually NOT depicted in the drawings.

For a more elaborate explanation of the operation, maintenance, tuning and fault-diagnosis on these carburetors, we advise the Haynes Weber Carburetor Manual which you can find HERE.

Click HERE for an exploded view drawing of the Weber DGAS and DGMS carburetors.
The drawing will then open in a new window.
You can use the <Alt + Tab> Keystroke combination to switch between the drawing and this page here.
The numbers in the drawing match the number prefixes in the part descriptions on this page here.
So, as an example, number 32 in the drawing, is article "(32) xxxx xxxx xxxxxxx" on this page here.

Please note that these carburetors can be equipped with two different floats; one made of brass or one made of plastic (or Spansil as Weber calls it nowadays).
These versions require different settings which you can find in THIS document.
