I bought the MS250 to replace my Husqvarna, which I had for almost 30 years. I found the MS250 easy to start in the beginning but, after a few uses it was becoming harder and harder to start until a month in it wouldn’t start. I took it back to the dealer and they replaced the spark plug and said the original Bosch plug was garbage. It started and ran for the first hour (with fuel fill ups of course) and after sitting for about an hour (lunch time) it wouldn’t start….again. I repeatedly tried and tried but, it wasn’t starting So, I emailed Stihl with my issues, they have not replied The dealer isn’t helpful at all and mocked me when I went in There is definitely something wrong with this unit and I will have to take it to another dealer for repairs and pay out of pocket to fix a one month old saw that is still under warranty In my opinion Stihl doesn’t stand behind their products and isn’t worth the cost and aggravation I miss my Husqvarna
