Weber IDA IDS Carburetor
The parts in this section are for the Weber carburetors used in Porsche 911 models.
Porsche factory-installed Weber carburetors on 911 models, 1966-71:
40 IDA carburetor used on the 1966-67 Normal 911 models
40 IDS carburetor used on the 1967-68 Porsche 911S models
40 IDAP carburetor used on the 1968 Porsche 911L models
40 IDTP carburetor used on the 1969-71 Porsche 911T models
Though all of these carburetors look similar and share many parts, they are very different in the calibration package installed and in the location and size of the progression ports.
