<DIV><BR></DIV>
<DIV>I've got a couple gallons through the new engine and I think it's
now properly broken in. The mid-range got a bit rich and clears abrutply
with a jump in rpm. I leaned the low end a little (from 12 to 1 o'clock
position) and the downline braking disappeared. Speed control with this set-up
is difficult. With the low end a bit rich speed is inconsistent on the
horizontal lines but downlines are good. With the low end a bit lean downlines
are too fast but the horizontal lines are good. </DIV>
<DIV> </DIV>
<DIV>I'm at 26.25" from the plug and turning the 15x11x4 at 8100rpm. </DIV>
<DIV> </DIV>
<DIV>Is there any benift to lengthening the pipe further? </DIV>

<DIV><FONT face=Arial size=2>What is the length of you setup from the plug
to the baffle inside? If I remember right the baflle is 15" from the
inlet.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Mine is at 26" from the plug and I finaLy was
able to get a real good down line braking and richen the low end
out. The Aeroslave pipe will make a ton of power in a
shorter length but the engine gets peaky and will come on the pipe or
really unload. One thing about this pipe. If it is
burbly rich in the midrange the length is too short.</FONT></DIV>

<DIV>Worked like a charm!!</DIV>
<DIV> </DIV>
<DIV>The engine ran flawlessly on the first flight after the run-in. I'm
using the Aeroslave pipe and 15.5x12 4 blade. I'm about 1 3/4 out with
the high end and parallel with the cylinder for the low end screw. All
seems OK.... good/slightly rich top end, reliable idle, rich in the
middle but accelerates with no problem, good downline braking. When
should I start moving the low end screw and where will the final
position be ...typically?</DIV>

<DIV><FONT face=Arial size=2>I am going to write a full "care and
feeding" article for the OS 140 for the July K-Factor, but here's a
good start.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>First, set your low end screw parallel
to the cylinder. 12 o'clock, straight up and down. leave it there
for the duration of the break in.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Use an APC 17x10N prop. use an OS F
plug.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>back the high end needle out 2 full
turns. if you plane has a chin cowl, remove it. This engine gets hot
for the first run or 2 on the ground.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Crank the engine with a very high idle.
Remove the igniter and then advance the throttle to full power after
about a minute. It should be spitting rich.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Turn the high end needle until it gets
some good RPM but still very rich. You should be putting out some
serious smoke. let it run this way for about 5 minutes, no
more.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Shut the engine off, and let it cool
for about 1/2 hour. the more, the better.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Fill the tank, crank it again, run it
to full. This time go in on the needle about 2 clicks and use that
for the reference. About every 30-45 seconds, lean it until it goes
to max RPM, and not ANY further. Let it run this way for about 5
seconds, and richen it back up. Cycle it this way for about 7
minutes. Shut down the engine, let it cool again.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Crank the 3rd time, and run it at the
same setting for about 2 minutes. Now lean it a couple of more
clicks, and it should be still putting out some serious smoke, but a
little closer to full. Step back, and let it run wide open for a
minute, then begin throttling it back and forth every minute or so.
Run the tank out like this.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>put it together and go fly it. Don't
touch the needle. When you get to the bottom of the 1st gallon, go
in with the needle ONE click every flight until you get max power.
When your low end changes, set the low end (always more lean, but
not a whole lot. When you play with that bottom end, a little goes a
long way. Like 1/8 of a turn or so.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>There are a lot of diffferent ways to
do it; some people just set it rich and fly. This way works every
time though, and the engines last longer.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>have fun,</FONT></DIV>
<DIV><FONT face=Arial size=2>-Mike</FONT></DIV>
