Overview:
This genuine primer bulb is designed for Walbro WA carburettors and many WT variants used on popular two‐stroke garden and light construction tools.

Dimensions are nominal Inner Diameter 14 mm, Outer Diameter 16 mm, Height 14 mm, with typical measured values of ID 13.8 mm, OD 15.5 mm, H 14.3 mm and lip 18.5 mm. Replaces OEM references 188-12, 188-14 and 4133 121 2700 for reliable, like‐for‐like performance.
