Question edited for clarity and all the typos. Question moved from Televisions to make model category. The whirling noise is the motor. It may be that the drive belt has broken? When was the last time it was professionally cleaned, serviced and timed? With moderate use, they need doing every 2 to 3 years.

Try these suggestions 1. Change the needle--use a needle that's for the fabric being sewed 2. Rethread the machine--top --make sure to use every thread guide 3. try a different bobbin--make sure bobbin is inserted correctly into the bobbin case & make sure the bobbin is turned the correct way in the bobbin case 4. make sure the thread has not come off the thread take up lever 5. Clean under the needle plate & in the bobbin area for lint or threads 6. Check to make sure the bobbin is not warped or damaged 7. Make sure the bobbin case is correctly in the machine,, if it's a top loading bobbin you may need to have the bobbin case checked to see if it's damaged or see if the hook and hook race has a problem 8. Also could be a timing problem, and the machine would need to be checked

Have you tried Alans Alterations at the MID WALES SEWING CENTRE they have a huge presence on ebay.They should be able to help you,or point you in the right direction.

try a different bobbinmake sure the bobbin in turned the right way in the bobbin casealso the machine may have a timing problem, and having it checked to would be a good idea.

From the reel on top, thread goes to the left and over the back guide and then to the front, straight down through the tension disc make sure the presser foot is up so the discs are open,round the first guide and back up to the takeup lever making sure thge lever is at the top, through the takeup lever right to left, straight down towards the needle taking in any cotton guides on the way and thread the needle front to back

From the spool pin take the thread to the left and over the top cotton guide, bring the thread towards you and straight down in between the tension discs, make sure the presser foot is up so the discs are open, straight down towards the needle and round the first big cotton guide, straight back up to the take up lever making sure the take up lever is at the top, right to left through the eye of the take up lever, straight down to the needle going through any guides on the way, thread the needle front to back

I've had that happen, here's 2 solutions, 1. put some tape over the **** in the take up lever--just make sure the tape doesn't touch the thread.2. very gently use some pliers and close the gap in the take up lever you might want to cover the take up lever with some cloth while your using the pliers to not scratch the take up leverI use to have a necci 4575, I did the first method for a while then didthe second suggestion. worked for me just fine.they are good machines, it was a work horse.

here's a link for inserting a bobbin into a machinehttp://www.youtube.com/watch?v=ZX3LjiYOLsghere's some links for a manual for the machinehttp://www.sewingpartsonline.com/instruction-manual-necchi-4575.aspxhttp://www.sewingpartsonline.com/instruction-manual-necchi-4575-download.aspx

it sounds like the feeddogs are in the down position, look at the area where the needle plate is and see if you can see the feeddogs?you can even run your finger over that area and you should be ableto feel the teeth. if you can feel the teeth or see them, then checkthe feed dog lever to see if it's in the up postion.the feed dog control lever should be in close to the bobbin area, the question is under the necchi 4575 catagory, so that's the information I'm putting in for the machine, if the lever is up then it'spossible that something is wrong with the lever or the feed dogsthem selves and they need to be checked at a sewing machineshop

Found this on another page http://www.fixya.com/support/t2568348-necchi_4757_need_know_way_needle- with many thanks to Paul Howell.I've modified it slightly for the 931

...Thread the machine from the spool, left to the guide on top/rear, over the top towards the front, around the tensioner down through the large channeled guide below it and up (picking up the thin wire guide on its way) around the take-up lever from right to left, down through the semi-hidden guide, through the needle clamp guide and thread the needle through the front to the back.

Firstly, the obvious stuff, is the needle blunt? This will caused skipped stitches; a needle is good for about 4-6 sewing hours or one project so needs to be changed regularly.However, if you have already checked that; then it is possibly a case of the timing being slightly out on the needle bar vs rotary hook rotation.If you look at this link, you'll see images relating to hook timinghttp://www.sewusa.com/Sewing_Machine_Repair/Sewing%20Machine%20Hook%20Timing.htmIt is something that can be tackled yourself if you want to have a go. But if the machine hasn't been serviced for a while, then its probably worth taking it in for a professional service and timing as the tech can check all the settings and clean and lube internally.

Sounds as though either the hook is out of time to the needle, or you have a bent needle. There are videos on Youtube that deal with sewing machine timing. Try a new needle, and make sure it is installed and seated correctly
