[NSRCA-discussion] Desperate

[JShulman]

It's been a loooooong time since the 4-strokes and I have worked well
together. Although the 200 ran great, that prop slip thing got me.

I think I remember seeing that the brass fuel nipples are all pinned and not
just the screw in type from way back. o-rings sound lie a good place to
start, but hopefully Troy (or someone more YS qualified) can give you
something else to look for.

Jason

  Jason,
  I'll try to track that down.  It seems that it's confined to the exhaust
side.  Very clear residue.  Exhaust...?  Raw fuel..?
  Man I just don't know...

    What about the o-rings around the valves

      I have a bad fuel/exhaust leak on my YS 1.60.  It started just before
my NMP header split but continued after replacing with
      a Hatori header and 821 muffler.  I'm getting pretty desperate trying
to find it.  I have replaced all the fuel lines.  I have snugged up
      the flange that screws in to the head.  I have retightened the header
flange.  I have checked the valve cover gasket.  I have checked
      the head bolts but it still leaks.  I consider the leak bad enough
that if I don't get it fixed by tomorrow I will have to miss my second
contest in a row because of it.  It really soaks the inside of the engine
compartment on the left (exhause) side.  Bad enough that when I run my
finger down the firewall it is wet with oil.  The engine mount beams on the
bottom sides are almost dripping.
      Any thoughts?
      Thanks!
      JLK
