Steve, See if the DC voltage on the VFO pot wiper terminal also 'warbles' - it may be hard to spot with a digital meter, if you have a fast reading analog meter, use that and see if the meter needle 'wiggles' What I am saying is that could be caused by a bad 10 turn potentiometer - the voltage at the wiper directly controls the capacitance of the varactors and therefore, the frequency of the VFO.
