I'd be willing to bet there is a small variable capacitor in the osc to 
tweak the xtal freq.  There should be a way to measure the L.O. 
injection freq just before the mixer stage.  Using a calibrated freq 
counter simply set the L.O. on the correct freq.
You did not say what band you're using for the IF.  Assuming 28 MHz IF, 
the L.O. should be 194.000 MHz. Good luck.  73, Bill, WF4R
