The primer (rubber "bulb") pumps fuel into the carburetor before starting the Partner 350 chainsaw and makes cold starting easier. Manufacturer: EMAST.
Replace it if it is cracked, leaks fuel, or the bulb does not return to its original position. Sign: hard starting of a cold engine.
The part is selected by the saw model name; if your saw has a different size, it is better to compare the old and new parts before installation.
