Thanks for the replys. I don't think I explained myself very well, I am trying to find out the difference in power between 2 stroke gas, and 4 stroke gas.
For example, isa Saito <span itemprop="name" style="font-family: arial">FG-21(1.26) 4-Stroke Gas Engine equivalent to a DLE 20 2 stroke in performance?
Are there any special considerations that need be taken into account when buying a gas 2 stroke vs a gas 4 stroke?

Thanks</span>
