I have a Walbro LMK Carb I took apart for cleaning. It is from a Briggs 16cvs. Somewhere in this shop, I misplaced the low speed fuel adjusting screw and spring. The Walbro Part number is 102-469-1. Tried to get a new one and of course it is no longer available. Since it had a limiter cap on it, they did not include it in the rebuild kit. Anyone have one laying around or a suggestion as to how I can save this carb?
