Hi, I'm new to the site and hopefully this is the right place for this question. I recently picked up an older husqvarna 61 (1989.. I think). It runs great, but I'm having an issue with the chain brake. While cutting with the saw, the chain brake is constantly engaging because the handle is hitting some type of adjuster or something connected to the brake(see the circled in red part of the picture below). I'm not sure if the handle has too much flex from old bushings, or what exactly this little assembly for the chain brake is for. Please let me know what it is and how I can resolve this issue. Thanks
