<DIV><FONT size=2>Thought I'd offer some quick set-up tips for anyone
interested. If you have an excellent system that works for you, no need to
read on. For those remaining:</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>1. Use a good hot glow igniter. The fuel injection
cools the plug more than conventional induction engines. You'll know if
you hear the engine pop, then no fire at all while spinning the prop and running
the starter battery (as the engine floods).</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>2. Set up fuel line/filter so its external about 2
inches (the holder can reach over and pinch line if engine gets
flooded while starting) Also the filter external is easy for maintenance
and diagnostics (those tiny bubbes from a faulty fuel line).</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>3. Start engine. Should start easily with a high
torque starter. Start with needle out quite a bit, pump setting
varies. (I have heard the recommendation of just a little
recessed; almost flush with screw housings, or, start with factory
setting).</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>4. If engine does not idle (loads up an quits after 10
seconds) screw the pump out. Mine took quite a bit out- about 3/4 turn out
from being flush with pump screw housing.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>5. With needle rich (I put mine out 2 1/2 turns) run
full throttle, then reduce back to idle, screw in a quarter turn, run full
throttle (you should hear an rpm increase). Keep doing this process til you
year that increase, go another 1/4 turn until it does not increase or starts to
knock. Then back off an eight to quarter turn. Note- during each
run-up, I'm not running at full throttle for more than about 3 seconds.
Why? So the engine does not over-heat if going in too
far.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>6 Fly. Great idle on the ground and excellent
runs.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>For reference, here are my settings. Fly JR,
Don</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Engine: YS 140DZ</FONT></DIV>
<DIV><FONT size=2>Prop: APC 16x12 (keeps prop noise down)</FONT></DIV>
<DIV><FONT size=2>Pipe; ES- XL (2C pipe) Less expensive and
quiet</FONT></DIV>
<DIV><FONT size=2>Fuel: Magnum Heli Pro</FONT></DIV>
<DIV><FONT size=2>Glow Plug: OS F</FONT></DIV>
<DIV><FONT size=2>Filter: YS </FONT></DIV>
<DIV><FONT size=2>Tank: Tetra 18 oz w/bladder</FONT></DIV>
<DIV><FONT size=2>Needle- about 1 5/8 out.</FONT></DIV>
<DIV><FONT size=2>Pump- about 3/4 turn past flush.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Discussion: The pump (turning it out) makes it pump with
less pressure, thus the need to screw out the needle. The less pressure
also results in leaner idle. Likewise, turning the pump screw in makes the
pump (pump more). Turn it in too much and the fuel line pops off at the
injector! No need for this much pressure. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Note on bladder- first one broke after 10 gallons.
Second one is still going. I now fill tank as normal, but as its getting to the
top, pump very slowly so the (balloon) is not too stessed. Fuel should
dribble out, interspersed with bubbles.</FONT></DIV>
