probably has about one hundred 12 minute flights on it.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The first trouble I noticed was that I had to trim the
idle up to keep it running but the engine ran strong at full throttle.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>After another 10 or 12 flights the engine would not
develop full power. Also, the high speed needle valve is more sensitive
where before it was difficult to tell exactly where the highest rpm
was. Also the idle has to be trimmed way up as the engine warms up and
it quits when trying to transition to high speed.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I have installed a new glow plug, adjusted the valves,
adjusted the high and low speed mixture with no improvement. I see no
air restriction to the carburetor. The fuel filter looks clean.
What should I try next?</span></font></p>
