<DIV><FONT size=2>All,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I purchased a used YS .53 a few weeks ago, I'm "NOT" a YS
expert by any means, but I usually get around them pretty well, I'm just having
some issues with getting her to run correctly.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Here is my problem:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>Prime the motor until fuel comes out the carb, and "1" flip,
it starts right up. The motor runs strong for about 3 or 4 minutes, but will not
idle below about 3300 rpm, it just dies. I have seen cases when the regulator
was sticking and causing a similar problem, so I loosened the reg screw a couple
turns, and I could see fuel move through the fuel line, I would then return the
regulator screw to it's proper place, it would run about 4 minutes, and the same
thing would happen.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I removed the regulator screw, o-ring, piston and diaphragm,
they where VERY gummy, so I cleaned them very well and re-installed. Motor runs
better, and will idle around 2500 as of now, but fuel POURS out of the carb even
if I have the throttle closed off.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV>
<DIV><FONT size=2>I'm using 20% Cool Power with added oil to bring the content
to 20%, and OS "Type F" plugs. APC 11x7 prop</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>The motor is set at 2 1/2 turns open on the High Speed needle,
and 1 turn open on the low needle.</FONT></DIV></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>The check valve I am using is from an OS 1.40, not a YS, there
was no YS valve with this engine.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Questions: </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>1 - Why the fuel pouring out of the carb ?</FONT></DIV>
<DIV><FONT size=2>2 - How do I get the idle better adjusted.</FONT></DIV>
<DIV><FONT size=2>3 - Should any further cleaning be done to the engine
?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Much thanks !</FONT></DIV>
