If I understand things right , you have a 024 top cover with markings on it,(name, number, initials, ext) that you know your father put on it. You have a serial number from stihl that says its an 026? How do you know its the same saw stihl has registered. If your mom cannot read the serial number, how can she tell one saw from another? I am not siding with the shop owners , if they did pull a fast one on your mother I hope they get what they deserve. Things just don't add up for you to make much of a case.
Yes, my mom has a cover plate that she marked after my father passed (assumed) and has had in her possession since his passing. It was purchased sometime before 1995 and (Stihl's) records shows a registration of a serial number in 1995. I spent two+ days researching an 024 model before finally asking Stihl about the situation and finding from them that he, my dad, had registered an 026 model. Yes, it was a bit shocking to find it different, parts are interchangeable as they are so similar and it has had plenty of use.
I'm sure that because of the time past, and services she has had to keep this saw tuned upped for use, she can keep a mental record of it over its use in time, she is not that incapacitated mentally, yet. I talk to her 2 or 3 times a week and keep track as it is a concern. The reason for her not reading it's number has been described in earlier posts, she does not have the necessary mechanical skills as some do for this. She is NOT a chainsaw user. If you people responding would please read and comprehend, she owns its and others use it for her needs, wood for winter heating! 90% of her wood, I or my siblings purchase for, but this years seems more difficult. She can't read the number because she doesn't know one part from another and the chainsaw is more dirty than she remember the one brought in, even though I've relayed the information from Stihl of where the serial number is located. My brother was going to use a carb cleaner on it, buy I didn't want him to do so (read earlier post regarding such!) I want accuracy to continue on and am seeking such. I don't know if a real switch was pulled until I get verification, and I want it from a competent source. Not my mom, nor brother, but someone who knows what they are looking for, and exactly where they need to look to find it. Also more on that in earlier posts. Things do add up, but answers given from the shop don't match when attitude is considered in.
Just alone, on its own merit, that chainsaw used before worked well in the past, now after it came back from this one shop, looks different, didn't run well, has caused melting of its known previous part marked, and now is non op. You tell me? I understand that everyone has questions, I have questions, but the facts are speaking for themselves right now. After the number is verified and checked, more questions will be settled. If my mothers feelings were not so involved, I would just simply just buy another to replace it, its just that simple. But if someone is taking seemingly helpless elderly for granted for their pitiful gain, I have issues, beside believing in her judgment for now.
I'm sorry for getting so touchy on this now, but things do seem to add up to me and until I get specific answers, I have to view the know and judge based on those known and continue, based on verified and verifiable facts. Please don't take this personal, but previous posters are showing bias' due to neglect to reading what's written, and/or, incomprehension of what's stated. I can only repeat so many times.
