Description
This WALBRO priming pump is an essential technical component for the reliable starting of 2-stroke engines equipped with compatible carburetors. It incorporates a fuel-resistant elastomer bulb with a precisely positioned orifice at the top to ensure optimal fuel transfer to the mixing chamber. Its strictly controlled dimensions (bulb diameter: 16.8 mm; base diameter: 21 mm) guarantee a tight fit on WT23A and WYJ series carburetors (WYJ33 to WYJ86). It directly replaces several original part numbers used on Stihl and McCulloch chainsaws.
