<DIV><FONT size=2>Tony, excellent. After an experence last weekend, I must
emphasize one other point- use the foam clunk pick-up, but avoid using
a standard clunk. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Spent an hour helping a gent after he lost a couple
of rounds at NARCA confirming the fact. Did save him an unnecessary
shipping charge back to YS. After fighting the engine for a dozen or so
flights for the past several weekends, he was happy to finally have the problem
solved by using the YS foam clunk. </FONT></DIV>

<DIV><FONT face=Arial>Don:<BR><BR>Good info for all.. However, the bladder
tank is not really needed.. Just use the pickup supplied by YS and it
will run just fine. Sure saves the worry about splitting a
bladder.</FONT></DIV>

<DIV><BR></DIV>
<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>
