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
