Description
Overview:
This carburettor primer bulb is a Genuine Ryobi part designed for Ryobi chainsaws, including PCN4040 and PCN4545. It replaces worn or cracked bulbs to restore dependable fuel priming before start-up. The clear, fuel‐resistant elastomer bulb and durable plastic base are built to handle regular use with 2‐stroke petrol/oil mixes. Pressing the bulb draws fuel through the carburettor, purges air from the lines, and helps the engine start more easily, especially after storage or maintenance. As a direct replacement for OEM numbers 5131000626 and 308088001, it offers the correct fit and operation without modification. Suitable for tradespeople and DIY users, this small part makes a big difference to starting reliability and smooth running.
