From what I have read about the 250's, on here they are a two-stroke engine. I'm ready to buy one and called the farm & ranch store that sells stihl and in their system they tell me it's a 4 mix. So my question is did stihl change the new 250's to a 4 mix ? I would have though they would of at least changed the model # if this is so ? Any body know for sure on this, or is it a type O their computer system.
