ECHO CS-310 CS-352 CS-353 ES SHINDAIWA 340S Chainsaw Primer Bulb + Pipe

Primer bulb and pipe fits Echo CS-310, CS-352, CS-353 (ES) and Shindaiwa 340S chainsaws, replacing part number 123181-39130. The primer bulb is the small rubber bulb mounted on the carburettor that draws fuel into the carburettor circuit when pressed, making cold starts significantly easier. The attached primer pipe connects the bulb to the fuel system. When the bulb is cracked, hardened or punctured, it can no longer draw fuel correctly, resulting in difficult or failed cold starting.
