Usually, after about five or six pulls, it would hit. A couple of pulls later, it would slowly chug to life until the excess fuel was expelled and then it was off to the races. I picked up a couple of Solo saws (650 and 645)really cheap. In my opinion the 645 is equal to the MS250 and the 650 will cut rings around it.
I have the MS250 and I will agree that it is very easy to flood. The trick with this chainsaw is that the first "hit" is barely noticeable. If you thought it may have had 1/5th of a first hit......that WAS the first hit. Switch it to half choke the first time you think you might have sensed a slight hit, and it will start on the next pull.
If you miss that, it's flooded.
