I had to wait over 3 weeks for a couple white solenoids for two 661's through my Stihl dealer.The harness issue is from the Russia war with Ukraine, from what I understand stihl is starting to get then made elsewhere. From my normal travels I haven't seen any real decline in mtronic saws vs what dealers ever kept on the shelf normally. Which in truth is a lot more then a year ago. 500i has become readily available as well as moat models being back in stock. Fourtantly the solenoids have little to do with where the harnesses are made so thats a non issue at this point.
Meanwhile two saws sitting unusable. I hope Stihl have a stockpile of solenoids stashed away somewhere that'll keep saws running way into the unforeseeable future.
