[Elecraft] K-2 VCO allign - help

[Smythe Family]

All has gone splendid thus far in the K2 construction.  That is, till now.
I am in alignment and test, 

Part II.  VCO alignment:

 

I have the correct slug tuned inductor installed at L30.  When I connect my
DMM to R30 (Lt side) and ground, VFO set to 4000 kHz, I get a reading of
7.95 volts.  Turning L30 (as you may have guessed) is doing nothing.  Am I
doomed to checking solders my entire Sunday (which is still more fun than
watching the Lions lose) or is there a usual suspect or problem spot?

 

Thanks
