FS: Weber 40 IDTP Restored Carburetor Set

This set of carburetors started life as a genuine set of Italian-built Webers that were delivered to Porsche for fitment in the new car production of 1969 through 1971 911 T Models. Both of these carburetor bodies are sporting the Genuine Porsche parts emblem stamped into the front of the main carburetor housing.
The Carburetor Restoration Process The process starts with a complete disassembly. This includes removing all the studs, throttle shafts, and throttle plates. The lead plugs that seal the progression port passageways are also removed to allow for the cleaning of the passageways.
Once the carburetor is, disassembled, parts are sorted into different categories. The steel parts are washed and inspected for wear and damage. The reusable items are sent to be re-plated to an original zinc finish. Zinc alloy parts like the auxiliary boosters and fuel pump distribution blocks and cleaned. Then vapor blasted, and media tumbled. The brass parts are also cleaned, vapor blasted, and media tumbled. Lastly, the aluminum throttle body housing and top plates are washed, and vapor blasted, then media tumbled.
Now that the carburetor bodies are clean, it’s time for the machine work to begin. The top plate gasket surfaces are machined along with the base gasket flanges. The progression port passageways are scrubbed with a small bottle brush to ensure that the passageways are free of restriction.

The top plate housing is also machined on both the plate-to-body surface and the air filter to the housing surface. The holes for the breather pipes are tapped to accept a new threaded breather pipe and new pipes are made.

After all the machine work has been completed, the housings are cleaned again to remove any debris from the machining process. New lead plugs are installed into the carburetor bodies, and the passageways are pressurized to check for leaks.
There are also limitations regarding how much protection a Cemfilm finish adds to the cast aluminum. In the last few years, we have applied a Cerakote finish to all the carburetor bodies we do. For carburetor bodies from 1969 and on, we apply a green finish.

The baked Ceramic coating provides superior corrosion resistance while maintaining the original look. Although we want the finished product to look good, we also want it to last another 50-plus years.
