<DIV><FONT face=Arial size=2>Hi Guys,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Need a little help/advice here. Trying to get
this YS-120NC running that I bought several years ago. I think it was
supposed to be new, but you know how that goes. I think it's a regulator
problem, but I have almost no experience with regulators. I'm sure you
realize how rare someone with YS engine experience is in and around Quincy,
Ohio!!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>First attempts--High speed needle about 2 turns
out. Regulator adjusting screw even with top of regulator housing.
Finally got a real rough idle (think I turned regulator adjusting screw in
slightly). Advancing throttle killed it right away, indicating a real rich
idle. I was tired and put plane in barn. While I was away all of the
unused fuel syphoned out of the tank on to the floor (no biggie,
remember it is a barn!). Hard to tell where it leaked out (inverted
engine) imagine it came out the carb intake, but it certainly came through
the regulator.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In desperatiion, yesterday I screwed the regulator
adjusting screw all the way in until it seated. Don't think I backed it
off at all. Engine started with a kind of rough idle. Transition to
full throttle (needle 2 turns out) was good. I didn't play anymore.
Imagine if I back off the adjusting screw to get a smooth idle, the unused fuel
will again syphon out of the tank.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So, you YS wizards, what do I do? If I
should replace the diaphram in the regulator, do I replace the spring
too? Guess replacing the gasket is a given.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Sorry about this, but I don't have anybody to talk
to.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks,</FONT></DIV>
