Fraudhacker no flanging

[MIYTADJ]

Built it. Passes signal and turning the bias trimmer makes it mildly flange.
Using the Frequency % duty setting on my DMM I can't get accurate clock readings (although this is the 1st time doing this and 1st time using freq. setting on my DMM. I'm not sure it's the correct function setting I even need . when I do use it on test point for setting the clock I get a reading then it goes to zero in like 2-4 seconds if I keep moving the probe on and off the test point fairly rapidly I get different numbers every time. keeping the probe on the test point and moving the trimmer changes the read out then goes to zero and to get a reading again I have to remove the probe and touch tp1 again which then goes to 0 in a couple of seconds. Is this normal . Are the sweet spots really difficult to find ? It seems the pedal just needs to be set up right and it will work but I have not heard any heavy flanging whatsoever which I'm sure is due to the trimmers not set properly
Can anybody share some working voltages To compare to and or shoot for? Or any ideas to look at ? I follow the calibration instructions and get nowhere. I must be doing something wrong I just don't know what.

 As always any help would be very appreciated. Thanks for your time

Which BBD and Clock chips are you using and have you tried taking any voltage readings on them?
