Found this on another forum (in UK posted about a week ago). The member indicated he asked Stihl (by email) about the 661 recall. Here is the response he received:
Thank you for your enquiry below, I apologise for the delay in my response.
The MS661 C Chainsaw was recently introduced to the GB Market, which was developed and produced with the utmost care. Despite this care, in-house quality tests have revealed few examples of malfunctioning engines in our first production run and very small number of cases have occurred in actual use. These problems specifically relate to the satisfactory performance of the engine. I must stress that it is not a recall.
STIHL is synonymous with quality and the complete satisfaction of our customers will always be our top priority. It is with this in mind we have stopped producing this model at this time.
If your machines have been running without issue, there should not be a problem with your MS661’s in use. However should you have encountered running problems from the outset, please refer to your local Dealer who will assess the item and seek our advice.
I trust this clarifies your enquiry, however should you have any further concerns you wish to discuss please do not hesitate to contact us.
Kind regards,
Claire Wells
