Thanks Scott for telling me about the website, hobbypeople are really offering good prices. Well, I hope I would be able to buy it from there or from my country. It's been a month I have been seriously trying to buy a 4 Stroke engine.
I have used on 2 stroke engines, I know one thing, once 2 stroke starts bothering they turn out to be a real problem, pretty hard to set them running good. About 4 stroke I heard that great Idle and best transition. Similary I've been told that 4 strokes are real Headache, once they start bothering you, then no way you can fix them. Specially their needles. I know there is one carb needle, other needle below it I saw and honestly I don't understand what does that needle do. I really wanna buy one 4 stroke engine and check it, that 4 strokes do run without trouble and they are not a HEADACHE, much better than 2 strokes. Should I really go for a 4 stroke? as I wanna buy ASP or Magnum which are same .91 4C engine for my 60 size easy sport. I would like to know the Pros and Cons of 2 Strokes and 4 Strokes. If I have repeated it, sorry for that.
Thanks in advance for recommendations.

I have 2 strokes and 4 strokes and dont find either one particularly difficult to tune. The 4 stroke is probably a little more so due to the fact that its harder to tune by ear. I generally use a tachometer to confirm my settings.
Unless you have run an RC engine too lean they should be good for years of flying without any problems. In fact after a good break in I rarely touch the needles except if there is a big change in weather conditions. I cant even remember the last time I adjusted the needles on my 4 stroke that I fly all the time.
So your comment that its hard to set them running well I wouldnt agree with. It just takes some experience. It would be good if you could work with an experienced modeler to get your engines running right. In my personal experience 90% or more of engine problems have to do with tank location or a hole in the fuel tubing. I have supertigre, thunder tiger, magnum and royal engines in various sizes and they all run great. In fact I havent had a dead stick in probably 9 months or so and I fly every weekend.
My personal preference is for 4 strokes I like the sound and throttle response.
