The YS guys are right about the power of those engines but I've really never seen one that didn't ask for a lot of tinkering.
That's the problem.... people tinker with them. If you have a good leak-free fuel tank and plumb everything exactly as the instructions show, a YS should be almost trouble free. I always staid away from them after watching guys struggle and hearing horror stories. Once I had one though I realized there was nothing to fear. Those people struggling just didn't pay attention to detail and made it more complicated than it actually is in their own head. Yes there could be a regulator problem from time to time but that's only after a lot of use (years?) and it is easily replaced.
I also like those new OS alpha series 4-strokes too. There's just too much good stuff out there.
I'm going to have to go ahead and agree with Chuck as never having had a YS of my own I only get involved with the 'Hey can you help me get this thing to run?' scenarios. It always amazes me that folks neglect to read the manufacturers instructions.....they apparently know more about engines then the engineers who designed them. That's not to say we all don't have our own experiences and preferences.
I have a reputation as 'the guy who stills runs in his engines' and we get a lot of laughs out of that around the field. The other day I'm breaking in a new Saito 1.00 and I hear the usual 'You don't need to break them in any more .... it's not a Fox .35! I pulled out 'the book' and showed everyone page 1 where it says something to the effect that you had better get 40 minutes on the engine before you lean her out and adjust the low end. Of course the 'experts' said "That must be a misprint". Hahahahaha. Did I mention I've had some engines for 20 years and they run better than new?????
