ok...even if the OS has a little bit more use than the SK?
I am still wondering something.... why is the SK harder to tune that the OS?
It's not. OS makes good engines, so do a lot of others. I've had an SK 50 for about a year, I have owned several OS and Super Tigre engines over the years. They are all good. 2 stroke glow engines are very simple devices, and most people can use them effectively with little effort. Some can't.
