Saw started after several primes and rope pulls. I am at 7000' elevation, so the carburetor may need tweeked a little, as it sometimes just dies, or dies when I press the throttle. Seems like it is getting too much fuel, flooding out. It has sufficient power if you go slow and don't force it, but I haven't tried it on real large trees yet. Anyway, I am satisfied with it, and recommend it..
