color=#8000ff size=2 PTSIZE="9" FAMILY="SANSSERIF">Lance<BR>I believe that
most problems that people have with YS four strokes are caused by them not
understanding the basic operation and feeding requirements of the YS design.
I had this problem when I first started running them, I had little help here
and went through the expensive learning curve. The best advice that I
can give to those that are new to running the YS four stroke is to use the
correct fuel and to never force it or run it lean. If it isn't running right
SHUT IT DOWN and find the problem. Most problems that I have found that can
ruin a good engine are not the fault of the engine but are caused by a fault
in the tank, or fuel system. most common of these are trash in the system
that fouls the diaphragm regulator or leaks in the tubing both of these
problems will cause lean run's and overheating that will damage the engine
very quickly the other most common problem is valve clearance adjustment
which will cause loss of power if they are loose or overheating and loss of
power if they are to tight.<BR>When these things happen the inexperienced
operator start's messing with the needle valve and regulator settings which
only makes the problem worse. After the engine is properly set up you rarely
have to touch anything except maybe a click or two lean or rich on the
needle valve.<BR>An experienced YS operator can listen to one and tell
immediately if it is running properly.<BR>After destroying a couple of them
during my learning period and stupidity some eight years ago I have run four
YS engines in several airplanes and logged hundreds of flights on them with
little or on problems. I recently purchased two new YS-140 Sport's and so
far these seem to be the best yet from YS they ran right out of the box and
seem to be as strong as the 140-L if not stronger and I didn't have to mess
with the pipe length to get them to run
right.<BR>Buddy
