Looking better. Where do you have your scope connected? Service info doesn't show waveforms so I couldn't say if it is correct.

B2 sets the frequency and is not in parallel with a fixed cap. I'd definitely check all the associated resistors and caps in that circuit if you're still not able to get a lock. Don't trust those 220pF mica caps.
