YS 140FZ Help

[vicenterc at comcast.net]

Set idle at 2000 rpm.  Observe if idle goes up or down during few seconds.  If 
goes up means that is lean and you have to richen the low end (reverse than 
other engines.  Richen by running the mixture screw in or clock wise).  If rpm 
at idle goes down the mixture is rich and you need to lean the mixture.  I have 
to FZ and they can be at idle at least 1-2 minutes at 2000 rpm.  Good start is 
1 to 1.5 turns out.

I didn't develop this procedure.  I read it in this group and used all time 
with very good results.  It works for L and FZ.  I don't think can be use in 
the DZ.

If you can not adjust after using this procedure, you will need to check 
gaskets for leaks.
