A 4-stroke engine is more complex to build and maintain, and will be somewhat heavier than a 2-stroke. It should, however, offer better power throughout the power-band. Most 2-stroke engines are built to run wide open (like a chainsaw motor - it's either running full throttle or idle). A 4-stroke will provde smoother power. |
First off
welcome to the forum.
Second, I think you better do some research because all 2-stroke motors are not made to be run wide open, outboard motors for boats are one example, and trials bike motors from the 70's are another example, also recent test on some of the larger 2-stroke outboard motors showed that they actually produced less pollutants than there 4-stroke counterparts.
