Ok - I made a video showing the threading and also the issues - sorry but been superbly busy at the shop and now me and the wife both REALLY need to get this machine working right for our own projects (bikes, cars, boats!)

Without the thread threaded through what I notice:

1. The thread guide is not original as their should be two separate thread guides that mount in the holes just above the thread tensioners.

2. Are you following the Singer Manual for timing? If you don't have the manual you can get one here  ( https://www.manualslib.com/manual/364320/Singer-112w139.html#manual )

3. To thread the needle you need to use the thread controller discs closest to you and the thread needs to go throw the hole in the take-up arm closest to you.

4. The spring in the thread controller seems to be at roughly the 7 pm mark and should probably be adjust to the 9 pm position.

5. To do the needle to hook timing slide the cover plate off so you can see the hooks placement in relation to the needle rather then trying to see it from the underside.

A photo of how you are threading from the needle would also be helpful. What system of needles not the size of needle are you are using as this can make a perfectly timed machine to not be able to sew.

I will shoot another video with cover plate off showing the hook timing slowly-

Not sure about the first tension disk route but the check spring is wrong you need to pull it up and towards the machine so the thread hooks over the notch and then down to the spring (you will notice a  fixed hook type bit at about 11 o clock the thread goes over)

Don`t go over the pin at the tension discs. Some folks do it (for what ever reason) but most don´t. In the manual the thread does NOT go over the pin. Then your bobbin case opener is not correctly adjusted, it does not pull back the bobbin case to make space for the thread to slide between needle plate notch and the small tab on the bobbin case . Reg. skipping stitches I would check the needle hook timing. I assume the needle bar a a little bit to high and / or the hook tip it too far away form the needle. You also have to check the check spring it appears to be set way too low.

Also when starting to sew hold the 2 thread ends slightly tense for 2-3 stitches.

Timing values are in the manual (guess you have one). If not I attach one for the 111G156 the values are the same as for your machine. Sorry its blurry cause I had to compress it. If you need a better quality PDF send me a PM with email address so I can forward it.

Reg. the check spring - check this (extract from the manual)

Totally agree with both the thread over the pin, which I have done on my machines with no problems but since you are only using one top thread have you tried using the other tension disc rather then the lower one as the lower one maybe worn and not releasing correctly. I would move the thread controller spring up more to the 9 oclock position.

Hi, sounds like a silly suggestion but is the needle scarf facing the hook?

[trash treasure]

Can you take out the needle plate and feed dog, and show us the needle / hook orientation, when the the hook comes around , and the needle has risen a couple mm?  No need to have thread in it for that - Just so we can see the actual situation.

Just because a local shop worked on it it, doesn't mean they had any clue - I've bought machines that were supposedly, recently "serviced", and they were way out of whack.  Just sayin' ........

Yep, same here. As Trash Treasure mentioned, have paid some big bucks to Repair People who didn't fix something, in fact made it worse.
