style='font-size:12.0pt'>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. <o:p></o:p></span></font></p>

<div>
<p class=MsoNormal style='margin-left:.5in'><font size=3 face="Times New Roman"><span
style='font-size:12.0pt'>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.<o:p></o:p></span></font></p>
