I have installed and run a whole bunch of Cline regulators on OS 1.60's with
much more success than the Perry's. Six of my own planes have used the Clines.
One thing I did with soft-mounted engines was put the needle assembly on
the firebox/wall rather than on the back of the engine.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The Cline needs you to prime the lines for the
first start of the day.This is done by putting a finger over the carb intake
and a couple of turns of the prop. I saw one guy use an ear-plug in the carb,
that he removed after the line had fuel in it.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I ran the Perry's, four of them, but they
would not hold their settings after about 200 runs. The Clines never changed.
(This is another of those religious wars BTW - the only real answer is to try it
for yourself and then decide)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I will argue that you need to fly a whole "season",
say 300 plus runs, before you know if you have equaled the reliability of a 4-c
YS, or what ever your goal was. I get the same thoughts when I see the twin-plug
head reports that say which plugs to run. I ran them for a year and they
didn't last more than 100 runs, often much, much less. You never know
if what you are being told was fully tested of if you are hearing a
short-circuit conclusion. A single OS "F" plug in an OS 1.40 or 1.60 should
last all year. A handful of flights is not enough to draw any good
conclusion.</FONT></DIV>

usually being run too hot.</FONT></DIV>

<DIV>Good point. No, I never tried in 2 C. I used the Cline
regulator long time ago in a Saito engine with not good results (sport
plane). Base on feedback from others those two system do not work
properly in pattern applications. However, any new feedback is
welcome.</DIV>

<DIV><FONT face=Arial size=2>Have you thought about switching to a Iron Bay

more like a YS than a Perry does.</FONT></DIV>

Regulation in 2C Engines</DIV>
<DIV><BR></DIV>
<DIV>
<DIV>
<DIV>Good morning all,</DIV>
<DIV> </DIV>
<DIV>I have been using the OS 160, OS 140 RX and Mintor 140 with good
results in the last 4-5 years. We have been comparing and discussing
the advantages of YS compared with 2C. One of the main
advantages of YS is that in transition when power down the engine goes
instantly to 2000 RPM or less. The 2C engines always takes too much
time to get down to idle and I believe that causes us (in pattern) some
problems. </DIV>
<DIV> </DIV>
<DIV>I have been thinking that the problem is that the carburetor and or
fuel system that can not regulate properly (pressure or flow). I
think in these engines, the pumps are set to deliver fuel at full flow (or
pressure) without any regulation system (like the YS). I had
the opportunity to discuss this issue with Perry Pump and they recommended
to install a by-pass line. The idea is to send the excess fuel
(pressure) back to the tank during transition. Perry Pump
recommended to install the T as close as possible to the carburetor needle
valve. Also in their web site they have an idea that he said is used
for cars that is a by-pass line that loop around the pump (<A
href="http://www.perrypumps.com/instructions.htm"
target=_blank>http://www.perrypumps.com/instructions.htm</A>, Click
on Pump and By-Pass Systems). I think the ideas deserve some
checking since it is natural to have this type of regulation to maintain
constant press! ! ure in the line before needle valve. I tried
the other day the by-pass to the carburetor but I installed the T too far
from the carburetor and forgot to open the vent in the tank.
Of course the results were bad since I was developing vacuum in
the tank. I will try these options of by-pass lines as soon as get
warmer. However, I think someone out there already tried to do this
and know results so I am looking for feed back.</DIV>
<DIV> </DIV>
<DIV>Thanks in advance,</DIV>
