You started your rant in post #3. You said you knew Husqvarna did not have any service manuals before you started the thread. After I told you there were no manuals available, at that point you went off on Husqvarna and others for not producing what YOU WANT. I don’t know what being an engineer has to do with your argument, but being an instructor in this field and just about the same age, plus working in this industry for 50+ years, I do know that what you want may not be available. I also taught my students that, “If you may get mad at the answer, don’t ask the question “. So I’ll repeat the answer I gave before you started your rant. THERE ARE NO MANUALS AVAILABLE.
