Feedback Problem

I have a tele style guitar (built from a kit), a fuzz/boost pedal and Fender Blues Jr III combo amp.
When I turn on the pedal, a high feedback starts.
I have several similar (tele style kit-build) guitars that do not suffer from this using the same pedal and combo amp.
It only happens if the pickup switch is in the neck (or middle) position, not bridge.
It can be stopped by turning right down either the volume or tone knob, or by turning off the pedal.

Any ideas how to solve this? I'd be so grateful for a fix, because the fuzz pedal and combo are staples of my rig. And this new tele sounds, looks and feels great... until I hit the fuzz.

Are you using springs or tubing for pickup height adjustment screws?

Thanks for the comments. The neck pickup is on springs. I raised it up a bit (because it was very low, quite flat to the body). But the feedback problem remains.

I'm wondering if it might be caused by the copper shielding tape. I shielded the pickup cavity, but the hole is quite tight, so I'm sure that parts of the pickup are pressed up against the copper tape.
