Missing clutch, now that`s a good one. I have been around repairing chainsaws for a long while, only one I can think of that comes close to that is. A Stihl dealer that is no longer in business was asked to do a tuneup and sharpen the chain on a customers saw, he bought it there 2 years prior. Its an 036 so quite a few years ago, left the saw there with instructions to be called when the saw is ready. A couple of weeks go by and he gets his call, saw is ready, its been tested out in the log out back, chain is sharp to. He picks it up two days later, pays the bill and heads home. He lives 40 odd miles down the Eastern shore from the shop. Next day gets the saw out to do some cutting,fills fuel and oil tanks, tries starting it and can`t even get it to cough. Pulls and pulls, lets sit in case he flooded it, pulls and pulls , no cough , no sign of it starting. He calls back to the dealer where the work was done, they tell him to try this and that with the choke, no choke, three pulls choke on , choke off, lada lada. Still no sign of starting, makes another call, shop says bring it back they will take a look at it. He agrees to take it back in on Friday as its a long drive and he has an appointment in Dartmouth close to that shop on Friday. On his way to the dealer he has to pass a small engine shop that does general repairs, he knows the owner and mechanic there so he drops in and gets to chatting. The mechanic says bring the saw in, he will get it started or see whats wrong, if it does not need parts no charge. The saw goes in, the mechanic pulls and pulls, no sign of start. He wants to check for spark so off comes the airfilter, goes ah ha, the sparkplug wire is not plugged on. Next goes WTF, where is the sparkplug boot, has to remove the recoil to look for the sparkplug boot, off comes the recoil, again WTF, the coil is missing.
Call goes into the dealer, coil is missing, dealer denies that was possible. Many calls and a few arguements ensue, the saw is taken back to the dealer. After a couple of hours the dealer finds out from one of the mechanics that is off sick ,that he borrowed the coil to try out on a saw he was working on at home. Mechanic gets fired, saw gets a new coil after a couple days wait for a new one to arrive and all is good with the world again. Not really, that shop over time got a bad rep and went downhill, eventually closing its doors.
