ABSTRACT:
A carburettor throttle member is provided with two return springs. The first spring is tensioned between the carburettor body and a disk rotatably mounted on the carburettor shaft. The second spring is weaker than the first spring and is compressed between the disk and shaft. The two springs tend to rotate the disk in opposite direction. The first spring normally retains the disk and shaft in a predetermined angular position. In case of fracture of the first spring, the second spring moves the disk into abutment with the fixed stop, operates as a substitute return spring.
