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>
