asking about the oscillating pump I believe - not the VP-30 . Jack - sounds
like there's not enough there with that pump - I would say use the VP-30
instead. I'm using a VP-30 and my main needle is about 1.5 turns open. That's
where you want to be. I actually reduced the pump pressure a bit too -
this helps the low end and mid range. The engine should NOT quit on the pinch.
It might speed up about 200 RPM but it definitely shouldn't quit. This means
you are way too lean (not enough pump pressure or volume). A VP-30 will
work fine.</FONT></SPAN></DIV>

<DIV>Jack,</DIV>
<DIV> </DIV>
<DIV>I have been flying the same engine with the Perry Pump for a long
time. Depending on temperature, prop and fuel combination, I am
usually between 1.0 and 2 turns. I believe that the combination is
very sensitive to the low end adjustment. Make sure that the low end
is as rich as possible for good transition from low to high as well from
high to low. If you lean the low end too much the engine will have
very poor down-lines. Base on my experience the best glow plug is OS
F. I use 20% nitro heli fuel.</DIV>
<DIV> </DIV>
<DIV>I have the following questions: </DIV>
<DIV> </DIV>
<DIV>1.- Is this engine new? If not and you bought it second hand I
will guess that you have bad bearings. The signal that you are giving
in your e-mail 3.5 turns open and not responding to needle valve adjustment
is one indication that you have bad bearings. In fly you will
notice loss of power. </DIV>
<DIV>2.- What pipe are you using? Make sure that you have at least 24"
between the plug and the first baffle. If the pipe is too short it
could cause the problem you described in your e-mail.</DIV>
<DIV> </DIV>
<DIV>You have a good engine/prop combination. The only problem with
the OS 160 is that it is very sensible to cold weather. It
definitively does not like to run around or below 50 oF. Usually
is fixed by richening both the low end and high end. That is good for
me since I am a tropical guy.</DIV>
<DIV> </DIV>
<DIV>I am sure that others will have more useful information. There is
more in the following web sites:</DIV>

<DIV><FONT face=Arial size=2>Does anyone know if the Perry Oscillator pump
has enough capacity to feed an OS 160 FX? Although the engine
seems to run OK, I'm concerned because the needle valve seems to be open
too far (about 3 1/2 turns) and requires large changes, like one
complete turn, to have any noticeable affect on the mixture
setting. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The engine will maintain full throtttle RPM
(about 8400 with an APC 17-10) without sagging (on the ground) and speeds
up a little before quiting when you pinch the fuel line. I haven't
flown it yet but I'm concerned that it may go lean in flight when the
engine unloads. </FONT></DIV>
