Please disregard. After I made the reply it deleted. I had tried for a
couple of days without success.

help</div>
<font size=-1>I can't tell from your description if you removed the
regulator body or just the adjuster screw. As viewed from side opposite
the regulator screw, the regulator is made up of a silicone rubber diaphram
(a thin disk), a brass plunger which passes through the body of the regulator,
the silicone fuel valve on the stem side of the plunger, the sping, o-ring,
and adjuster. From your description it sounds like the small silicone fuel
valve on the stem side of the regulator is missing/damaged, allowing pressurized
fuel to pass freely to the carburetor. Check out this picture at Central
Hobbies <a href="http://www.centralhobbies.com/Engines/parts/YS140LEX.htm">http://www.centralhobbies.com/Engines/parts/YS140LEX.htm</a>
It has a clear picture of the regulator parts. (The YS53 picture shows
the plunger on the wrong side of the regulator body) The plunger and the
fuel valve are sold as a unit under one part number. It and diaphram
should be clear or nearly so (like clear silicone sealer looks when dry).
If it is gummy, the goo you found could be the result of petroleum based
after run oil. You should replace the diaphram and the plunger</font>

<font size=-1>All,</font>
<font size=-1>I purchased a used YS .</font> <font size=-1>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> <font size=-1>I'm using 20% Cool
Power with added oil to bring the content to 20%, and OS "Type F" plugs.
APC 11x7 prop</font> <font size=-1>The motor is set at 2 1/2 turns open
on the High Speed needle, and 1 turn open on the low needle.</font> <font size=-1>The
check valve I am using is from an OS 1.40, not a YS, there was no YS valve
with this engine.</font> <font size=-1>Questions:</font> <font size=-1>1
- Why the fuel pouring out of the carb ?2 - How do I get the idle better
adjusted.3 - Should any further cleaning be done to the engine ?</font>
<font size=-1>Much thanks !</font> <font size=-1>________________________________________</font>
