A two stroke is like a whiney little four banger Honda. You must wind it up high in order to get usable power. On the other hand, a four stroke is like a throaty V-8 or V-12. It has lots of low end torque and sounds good no matter what muffler you put on it. It's hard to make a Honda sound like a Corvette or a Ferrari.

All my engines are four strokes, and I love them all.
