My surjetteuse does not make its curls anymore

When the needle broke, it probably knocked the machine out of time or possibly caused a burr/rough spot. Take it for service.

Replace the needle.....if that fails....Timing is out

Here are the basics...or time for a Service

Not sure if you have looked here but I posted it anyway... Hope it helps.

it's very possible that when you broke the needle it caused the machine to go out of time & would have to be retimed at a sewing machine repair shop

How to Thread Juki MO-134 Serger from watching lady at Lyles. Turn upper blade up. Push in first then turn up.It makes threading easier. Blue Thread upper looper first. Pull thread through tension knob. Don'tjust lay it there. (She thought that is what I must have done) Orange Thread lower looper next. Pull thread through tension knob as inthreading upper looper. Adjust lower looper so it is right nextto upper looper so that their points are almost together and directly belowsewing needles. Lower looper will be in front of upper looper (I believe). With tread from upper looper pulledback, slightly lift lower looper above upper looper and thread. I think this isright. Pull thread back with other thread. Tension is the key. Remember that. Yellow: Thread left needle first.Remember tension. Pull thread through curled wire on left side of needle arm. Green: Thread right needle. Rememberabout tension. Pull thread through curled wire on right side of needle arm. b> Note: Before sewing turn the wheel tomake sure the stitches are going together correctly.

Check the manual for maintenance infromation.

Noise can be from lint in the bobbin area.

After cleaning, re-thread the machine with the presser foot up to see the combination of cleaning and "presser foot up" threading helps.

Singer sewing machine needle does not go directly down into opening of foot, it hits the back plate of foot. how can i align it.

Is the needle in right? There is a front and back to a needle. Also is it the right needle for the machine?

Presumably neither of you has or knows how to adjust your bobbin tension so, I'm going to presume it's your hook. Make sure you are threading the machine coorectly then you'll need to remove your needle plate by removing the two screws, pull out your hook (this is the part your bobbin sits in) but make sure you note which way it sits inside your machine. Have a look at the plastic hook for any sharp edges or burs, you may need to replace your hook or try and gently sand (400grit) the plastic if possible. The key part of the hook is the small blunted point as this is what catched the loop of thread behind the needle. Please make sure that when you put your hook back in, that it is on the left side of that little guard sticking out on the lower right of your machine.
