sounds like a darn good place to start looking.  But the right way to
test the WUR is with a fuel pressure gauge set.  The control pressure
should start when cold around 50 psi and drop to about 15 as it warms
up.  This lowers the fuel flow at the metering head and leans it out. 
Pressure figures for illustration only, check the manual for correct
numbers (and where to hook up the gauges).

good luck!
