This blower was use maybe 2 hours and having problem revving up.Air filer clean, checked spark plug good. Question i have who selling that specials tool to adjust carb.Thanks for help.
Strange Echo is listing a Walbro WYK-387 for the PB-760LN(T) or PB-760LN(H). What is your serial number but if the ones I checked there is no listing for one using a WYG.
The service manual does list a small D tool for the idle mixture setting but that tool is not available to the general public from Echo. You search for 2 cycle carburetor tools on Amazon it show up several kits from China that would have this tool.
