Backwards only? UGHH! I turned it forward quite a bit so did I cause a bigger problem? The Handwheel spring isn't on the cylinder correctly, at least I don't think it is. It's not all the way towards the back.
As for cleaning it, I did use the Bernina oil that came with it. It was still nice and clear and didn't appear to be glunky. I used a toothbrush to try and clean anything that did look like glunk but the parts inside are close together and I'm no expert by any means to start removing screws to get to something. Mostly I found lint and I have the manual the machine came with and a few youtube videos watched so I believe I cleaned it fairly good. Can I take off the bottom fairly easily to get any lint that fell down? For the most part I believe the 1st owner took extremely good care of this machine, she gave sewing classes. The second owner, not so much.
I am unable to take it to a tech at this time. I have 3 working machines that I can use for now, mainly my big beast of a Kenmore but the Bernina is sitting there taunting me. Like a kid in a candy store. I wish I would have known about the wheel only going one way. That speaks volumes about it's quality. No humming when you step on the gas lol.
