<DIV><FONT size=2>I too was told that. However, turning down the pressure helped
me. I also turn the pressure down on my L's. I know that around 2000 RPM and
below, the pump pressure is not to be a factor, that is why they tell you to
work you idle adjustments the way they do. Set the High speed needle first, then
bring back to idle so it hits 2000 instantly. Then observe if it speeds up
immediately or slows down. If it speeds up at first then dies, it is too lean
and vice versa. Above approx. 2000, it is working off of tank pressure.
</FONT></DIV>
<DIV><FONT size=2> I hope I remembered the suggestions
correctly, my earlier recommendation worked for me. You didnt say, however, if
the engine sped up at first, but you need more nitro none the less. Good luck,
Terry</FONT></DIV>

<DIV><FONT size=2>I've got 15% cool power (green), guess I need to get some
fuel with more "oomph". I'm going out to mess with it tomorrow and will
try the regulator. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I was looking on the YS engine forum on RC Universe and Dave
Shadel stated that the regulator doesn't have any influence on the top or
bottom of the RPM range, only the mid-range. Can anyone else here
confirm that??</FONT></DIV>

<DIV><FONT size=2>You might try turning the regulator in. To get my 91AC to
idle, I had to turn the regulator in nearly 3/4 of a turn and idle out 1 1/2
turns. Ran great after that. What nitro are you running? You need a minimum
20%, and 30% is better yet.</FONT></DIV>

<DIV><FONT size=2>Yup, got that. . . left is lean, right is rich. .
. Just came in from messing with the low speed needle and it is set
good for the transition, but it still won't idle for more than 20-30
seconds. I run it full throttle for about 10 seconds to pressurize
the tank then drop it to idle - 2000 to 2400 RPM. The engine idles
at this speed for about 20-30 seconds then the RPM slowly decays until it
quits, then fuel drips out of the carb (engine inverted). I
relight the glow plug, spin the engine and it starts right up again and
repeats.</FONT></DIV>

<DIV><FONT size=2>Low speed is an airbleed. Out is leaner, in is richer.
Opposite from the high speed.</FONT></DIV>

<DIV><FONT face=Arial size=2>Gentlemen,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> I'm breaking in my YS .91FZ
and seem to have gotten the top end working fine, but the engine idles
at 2000 RPM for about 10 seconds then slowly dies. I don't
remember which way to turn the low speed needle, and the YS
Performance page seems to have been hijacked.
Thanks!!</FONT></DIV>
