Mixture adjustment tool for Weber 36 IDF and 40 IDF 68/69 carburetors

The mixture adjustment screws on Weber IDF carburetors are notoriously difficult to access, especially on Beetles. But this small tool makes adjusting them much easier. Furthermore, it has the advantage that the adjustment screws cannot be overtightened in the brass seat, as the tool cannot apply enough torque to damage the carburetor.
