Here's a little item for you. A four cycle engine does not have more torque than a two cycle. It has a higher BEMP, brake effective mean pressure. A two cycle firing every stroke has more torque.
Doesn't the 2 stroke have to be doing more revs to produce the same torque? I was always lead to believe that the 4-stroke would produce better torque at lower revs, making it more suitable for swinging larger diameter, lower pitch props.
