A few months ago I got a Stihl Kombi 131R (the big one), and really like it. I'd like to add the blower (BG-KM). But when I was reading reviews I saw several reviews saying they've broke the shaft inside with when using it with a 131R. At least one reviewer claimed to have broke more than BG-KM. This includes the reviews on Stihl's own site. I've emailed Stihl twice asking about this and asking if they have already or are working on a design update. They did not reply. Leaves are falling and I'd like to buy a BG-KM... Are any of you running this combination? any issues? Or has anyone looked into it and figured out its a non-issue?
