The decompression valve is part of the easy start-system. The valve should be pressed before starting to cut the compression pressure when starting, as well as the effort needed to pull the starter rope. The decompression valve is semi-automatic, meaning that it must be pressed manually before starting, but then closes automatically.
This controller in the carburetor prevents the fuel-air mixture from getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburetor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn’t need to be cleaned until an appreciable drop in power occurs.
All important functions such as start, choke, throttle and stop are operated via a single lever.
