I accept with information: 2 stroke engines are easier to maintain (less moving parts - no valves, no oil pump, etc.) However, they are less efficient and much worse for the environment, because there is constantly unburned oil and fuel passing through to the exhaust.
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.
