In case this helps anyone else, I believe I have solved the issue (at least in my case). The saw is an Echo 620sx. The metering lever was set too low, which results in a lean condition which is most obvious at idle. I adjusted it according to the Walbro HDA manual. I've not tuned the saw in wood...

Hi woodshed, did you ever solve this issue? I have exactly the same problem with my saw. I've replaced the pump diaphragm (albeit aftermarket) and it does not seem to have made a difference. Saw runs fine otherwise, just starts idling high when left for a few seconds after cutting. Cheers
