If the engine is not running as sweetly as it once did, have you thought about a complete carburettor overhaul? The component shown in the image, is just one item of many you may require to achieve smooth running and first prod starting.
Surprising (and pleasing) results can be achieved by a complete strip down, sonic cleaning of the carb body components, then new jets, springs, float, seals and O-rings reassembled into the carb/s.
