now that i dont get. 4 strokes arent nearly as good as a 2 stroke pros/cons are better for a 2 stroke well for a avergae family.
a 2 stroke has higher rpms, cheaper, less parts, but are louder and worse for the environment where as a 4 strokes is vice versa for all. an average family that will own a 2 stroke weed wacker, chainsaw or w/e it may be will drive there car more which will probly add up to the polution there car puts out in a week to the polution there equipment will put out in the time they use it
