YS Engines

[Bob]

Eric and the gang:
 
Consider the following:
 
    YS 120 (Don't know whether AC, SC, NC, or any other designation YS may
have)
    Runs great top end and idle and transition
    Needle valve is bottomed out, all the way in for near peak power (still
a tiny bit rich)
 
Question:  What's the problem with the needle valve?
 
Thanks guys in advance for any advice.
 
Bob

To answer the question. "Ok, time for another newbie question: it seems to
me from the discussion and contest results and a few copies of the K factor
that Kane gave me at the D4 contest last year that pattern pilots prefer YS
engines, yet YS engines don't seem to dominate in other kinds of
flying(IMAC, scale, fun fly, etc). Um, why?

basically:-
1. YS engines are too small for IMAC and teasingly so too quiet :-)
2. Fun Fly's are not a 1.40 type event if you are talking wild tasks?
3. Scale is not an engine power event.
 
Regards,
 
Eric.

Ah yes! ... the subtle distinction between complication and sophistication.
Do you notice, though, that the guys who had their 4-Cs running well art
generally the guys with the nicely running 2-Cs?
The question is not, "What to run?", but, "How to run it?"
Somewhere at the beginning of this thread, someone asked what he should run
... and one workable answer might be to latch onto someone local who has got
his act together, and learn from him. This may not involve duplication,
either.

    Dean

Simplicity is not a word you want attached to your high-tech pattern
aircraft anyway....

Jim,
I'll bet by now you can assemble and disassemble the 15 moving parts that
make up just the head of that engine with your eyes closed.  It's a zen like
procedure that brings comfort and joy.  
  My engine only has one part (glow plug) and it doesn't move.  while you're
doing that I'll have to find something else to tinker with....[where's the
wife.....]

Guess I am getting soothed then. I just started the 3rd rebuild on a YS
140L.It has 450 flights on it.

something, or doing periodic maintenance, they feel lost.  Therefore, YS
engines help soothe the pattern mind.
