I recently brought my Stihl FS85R trimmer to a Stihl dealer to be diagnosed as it would not start. The clutch is starting to wear but is still a great machine with 110 psi compression. I knew it needed a new pawl (41331957201) and spring (00009980612) in the recoil and had left 2 of the 3 screws fastening the recoil loose (the third had vibrated out) to facilitate installation of the new parts. I was told I had to pay a $20 deposit upfront and that that money would be applied to any repairs if I chose to have the company fix the trimmer. If I did not want them to go ahead with the repairs, then they would keep the $20 for their work in diagnosing the problem. Well, I did not get a phone call telling me what was wrong with the trimmer and the expected option of wanting it repaired or not... Instead they phoned me and told me it was fixed and that I owed them almost $40 more! I was surprised when I saw the bill, as three quarters of an hour was spent to install a new pawl and spring and to tune the carburetor!! I would have expected the installation of the pawl and spring in the recoil to not take any more than 5 minutes (remove the 2 loose screws, install the pawl and spring, get a new screw, screw in the 3 screws). Similarly, the tuning of the carburetor I think should not have taken any more than 15 minutes. What I would like to know is, what is a reasonable time to expect to have this work done? I am not an expert in this area of service. Perhaps my expected times of repair are not at all accurate. I can understand a repair shop wanting to charge a minimum for looking at the trimmer. However, If that is what they are expecting to do, then I think that is something that should be explained clearly upfront and secondly, it should be described as such on the bill. Is 45 minutes really necessary to install the pawl, spring and tune the carburetor? Or does it really only take a fraction of that time and I was subject to a minimum shop charge or was I just treated unfairly? Thanks for all feedback.
