<DIV><FONT face=Arial size=2>Hi Paul..</FONT></DIV>
<DIV><FONT face=Arial size=2> A couple of thought I can share
with you.. If you are still using the same glow plug you broke the engine in
with I would suggest changing it. They get pretty nasty quickly when
breaking it in. </FONT></DIV>
<DIV><FONT face=Arial size=2> You may want to add a header
tank close to the engine and in line with your needle valve. Do you always
shut the throttle trim to low including idle trim when you shut down.. If still
dripping confirms to me you are having gravity force fuel through the carb and
it isn't totally closing its fuel flow. I have used hemostats to clamp the feed
line to the carb. when I wanted to make sure not to flood and invertered engine.
</FONT></DIV>
<DIV><FONT face=Arial size=2> I have never run the Mintor and
not familiar with its appetite for fuel but I am guessing you are a tad on the
small side with a 16oz tank. </FONT></DIV>
<DIV><FONT face=Arial size=2> Others may have more info
to help you.</FONT></DIV>

help</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have a Mintor 140 in a Patriot, using Mintor's
header and carbon fiber pipe with ~1/2" between the header and pipe, turning
an APC 17-12N. I have just broken it in running 5 tanks (14 oz ea) of
PowerMaster 15%. I am running it on the rich side, turning about
7000-7200 rpm. After starting the engine, I run it up for a few seconds
before disconnecting the glow plug, then I bring it back to a fast idle (~2200
rpm). By the time I get it out to the flight line to take off (a few
seconds), when I open the throttle it loads up and dies. I have started
to lean out the idle mixture a bit and this seems to help. I am a little
hesitant to lean the main needle further - I had to replace the
piston/ring/cylinder liner due to previous lean runs (entirely my
fault). Once I get it in the air, it seems to run fine, but the fuel
seems to run out quickly.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The other thing that is happening is that the
carb drips a bit after I fill the tank. It was much worse when the tank
was above the wing tube, but I repositioned the tank in front of the wing
tube, as low as possible, and it isn't as bad as it was. This is a 16 oz
tank.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My plan is to do the following:</FONT></DIV>
<UL>
<LI><FONT face=Arial size=2>Start the engine, run it up to full throttle,
monitor the rpm with a tach, then turn in the main needle until the rpm
peaks and then drops (indicating lean), then richen it 3 or 4 clicks.
I'll try to fly it like this and see if I have the same problem.</FONT>
<LI><FONT face=Arial size=2>If it is still loading up on idle, then I'll
lean the idle mixture further and repeat the previous step.</FONT></LI></UL>
<DIV><FONT face=Arial size=2>Is this a good approach? Any other
thoughts?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks.</FONT></DIV>
