<DIV><FONT face=Arial size=2>One more thing you might check, if the engines have
set, sometimes the metering slot in the barrel will get "goo" in it and will not
allow fuel to flow freely. Try cleaning the throttle barrels metering slot and
other passages. Had this happen to an old YS 60 years ago.</FONT></DIV>

<DIV><FONT face=Arial size=2>Hello! I have the exact
same experience while helping a new pattern flyer set up his YS .63 just
last week. The engine would run fine at half to full throttle, but in
the air if he went to idle any more than about 4 seconds the engine would
quit. All you need to do is turn IN the little air bleed screw on the
side. Try turning it in about 3/8 to a half turn to start. You
should find good results at this point.</FONT></DIV>

<P><FONT size=2>Quiet in here..<BR><BR>Tried to help a friend out at the
field on Mon with a pair of YS63's on a twin. Flew fine on the first
flight several months ago, but both of them now will not hold idle when he
pulled the plane back out this week. They mostly run at 3000 up,
just abruptly die below that.. Like fuel starvation. If you punch
the throttle hard, the engines would usually backfire and immediately die
unless you ran quite rich. Looks like he may have had a cooling
issue on both engines (no cowl air other than valve cover). Both
engines doing exact same thing. Possible heat
damage? Something ate both regulators? I ran out
of ideas.<BR><BR>Not a pattern plane, but there is a lot of YS knowledge
on this list.. Any thoughts?<BR>TIA, Chuck</FONT> </P>
