mid range loading up problem</DIV>

<DIV><FONT face=Arial size=2>Hello All,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I need some of your expertise. I am
having trouble with my OS 1.40 RX loading up in mid range. The
engine has 5 flights and approx 2 gallons of fuel through
it. I am using an APC 16 x 14 prop, OS T-6010 Tuned
Silencer, tried the A5, #8 and type F plugs (no difference), Magnum fuel 10%
nitro with caster/synth blend, pipe set for 8000 rpm, and using the short
needle valve. The low end idle adjust screw is adjusted all the
way to the lean (all the way in) which is necessary to idle smoothly.
Transition quickly from idle to max throttle isn't too bad but slower
than I would like. If I set the throttle
at 30% to 50% it loads up and and slows in RPM. In
transition from mid to high throttle the engine vibrates and
burbles for 3 -4 seconds before it clears and comes on the pipe,
it has even stopped running a few times. I have read that some folks
use the longer needle valve and higher nitro to minimize this problem, but I
haven't tried that yet. From those of you who have experience
with this, what is going on, and what are my
options?</FONT></DIV></FONT></DIV>
