Description
Overview:
The Walbro Primer Pump Bulb with a 24 mm (0.94 inch) diameter base is a genuine replacement part for small petrol engines. Made from clear, fuel‐resistant elastomer with a rigid collar, it draws fuel into the carburettor and purges air from the lines, helping engines start promptly and run smoothly. It is suitable for many Walbro and Zama carburettors commonly fitted to handheld and compact outdoor power equipment including chainsaws, brushcutters, trimmers, hedge trimmers, leaf blowers, lawnmowers and small pumps. The dome‐shaped bulb gives positive feedback when pressed and its transparency lets you confirm fuel movement during priming. Supplied as a Genuine Walbro part (MPN W188‐13), it offers reliable fit and performance when replacing a worn or cracked primer.
Key Features:
- Genuine Walbro part for assured compatibility and quality

- Works with many Walbro and Zama carburettors on 2‐stroke and small 4‐stroke engines

- Durable construction to withstand repeated presses and workshop handling
- Restores easy cold starts and reduces excessive pull‐starts
- Smooth, light action with quick rebound for efficient priming
- Straightforward replacement on most carburettors; no special tools in most cases

Typical Applications:
