The 4 has a greater life and low end torq and is possibly cleaner.I've heard
I'm not so sure about the greater life claim. They are all rated at 600 hours and typically do 2 or 3 times that amount in real life. I think the 2 strokes are MUCH better at staying at top rpm - they are designed to be run wide open. The 4 strokes really aren't. The torque peak on the Honda is at 5500 rpm's, so it's not like it's building tons of torque at idle. Hehe. My Mitsu idles around 3000 rpm's and pulls up to over 8k (I saw 8,500 rpm's yesterday). The 4 strokes probably ARE cleaner than the 2 strokes, no doubt, but the Mitsu is clean as far as 2 strokes go.
