Echo chainsaw won't idle
I got a chainsaw that starts easily and runs well at high speed. It will go down to low speed and rev up again if you catch it fast enough. But it won't idle for more than a second or two.
Took the Walbro carb off and found not a speck of dirt inside and blew out the passageways. The only thing I saw was a slight crinkle in the diaphragm, but it appeared to be like new.
Put everything back together and it has the same problem. Plug, air filter are new. Hi and Lo settings are limited. Muffler is clean. Gas is clean and primer works.
