<DIV><FONT face=Arial size=2>I use the cline on a Webra 145 with the Greves pipe
set-up and it works perfect.Take the pump off and replace it with a
standard backplate and install a pressure nipple in the backplate.Install a
check valve and you have a YS regulator setup,basically.</FONT></DIV>
<DIV><FONT face=Arial size=2>Mount the regulater as close to the carb as
possible.I mounted it on the side of the motor mount. This setup spreads
out the needle sensitivity and makes the needle not so touchy, as it is,
with the pump pressure on both low and high adjustments.</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
or Cline regulator? It's a thought, I believe these systems operate
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>
