I have a 240. I don't think it all that. I do find it powerful but am having a hard time with throttle response when running a blade. Admittedly, that is because I messed with the screws but I haven't gotten to tune it out. Power is very good, runs a shredder blade just fine. Fs130 has more torque, imo. But the Fs240 doesn't seem to be the most powerful at the top end. It also doesn't come with much. You get a powerhead, trimmer head,(cheap) harness and safety glasses. You have to buy any blade and the limit stop (saw blade guard) seperate. It adds up. A Husqvarna 336FR should come with everything. Tri blade, saw blade, trimmer head, harness etc. In the USA that is. What is available in Canada?
Are you dead set on Stihl? If you are get a FS130. If you want a 2-stroke, I would look at Husqvarnas offerings. It is hard to get over the torque of a 4-mix. It really sticks with you.
