I have not tested these carbs since finishing my project, so the condition of internal parts is unknown. Feel free to ask questions. Matched pair of Weber 40 IDF 70 carburetors I used testing on a motorcycle project 1300cc Yamaha Venture years ago. Should be great on VW Beetles, buses, Porsche 914's, some Fiats and Alga Romeo's.

Examine the photos closely, what you see is get. They worked perfectly then and haven't been used since so a good cleaning is recommended applies to most carburetors of course.
