<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>
