What year this Montgomery ward chainsaw was made and how do you adjust the carberator model 24040c?

The Montgomery Ward chainsaw model 24040C was typically produced in the late 1970s to early 1980s. To adjust the carburetor, locate the adjustment screws for idle speed (T) and mixture (H and L). Start the chainsaw and let it warm up, then adjust the low-speed mixture screw (L) until the engine runs smoothly, followed by adjusting the high-speed screw (H) for optimal performance at full throttle. Finally, set the idle speed screw (T) to ensure the chain does not move when the engine is idling.
