Just bought a 310 last fall. Oddly the dealer tried to push a 24" bar on me but I only wanted a 20". I haven't used the saw much yet (bought it after seasons wood was in) and so far I am not impressed. Doesn't seem to come up to speed and bogs easily. Break in problem? Carb? I would hate to see what it was like with a 24" bar.

How wrong I was. That saw ate acres of trees, rode hard, put away wet and the max dealer recommended bar was 24". I ran 24" in softwood trees where I had to cut from bot h sides and a lot of Black Locust up to 3' diameter. I rean it until i bought a MS362,...then a ms441. Still took it out occasionally. Last time I used it it had very low compression but once started was still eager. I gave it to a budy whose 024 died on him. He has it as shis main saw now even with the low compression.
