The 12-b57 is a throttle lever for Marvel-Schebler MA-3 and MA-4SPA carburetors. This mechanical component connects the throttle shaft to external control linkage, enabling pilot-controlled engine power modulation. Constructed from durable aluminum or steel, the lever transfers manual input from the cockpit throttle control to the carburetor's throttle valve.
Installation requires proper rigging per the aircraft maintenance manual to ensure smooth throttle response and full range of motion. Commonly included in Marvel-Schebler carburetor repair kits for piston engine aircraft.
