I can only put a paperclip
through one of mine. So, what are 'slip adjustable pliers'?
I'll go ahead and operate on this one, plus the one that has the loose positive block. The rest will have to wait, in case they work fine the way they are.
By any chance is there a video?
Looking at the google images of spare parts to try to imagine how it really works, I'm amazed the ones that aren't lined up with the hole in the positive pin actually work at all. That's where all the airflow comes from!
The air goes into the hole in the pin, then flows up the tube in the center of the pin up into the chamber. And, comes out under the coil. So cool to know how things work!
However, to make them actually work right is not my strong suit. But, I'll give it a try. Any videos to watch (to see what to do and what not to do, and to give me courage)?
