I was gifted a huskylock 431 serger. It does not have a foot and I broke the needle trying to figure it out. Is there anywhere to buy used or compatible parts?

Threading Serger this may be helpful even if it is not the same model. The sequence of threading loopers is VERY important. If you thread them out of order, be prepared to be frustrated beyond belief!!! Something else (I don't think she mentioned) is to ALWAYS RAISE the presser foot when threading your machine. This is true for sergers AND sewing machines!

Most sergers/overlockers will come with a tool kit including a small flat blade screw driver and a set of tweezers. Both are needed to change a needle along with a steady hand and glasses in my case.

Turn the flywheel towards you until the needle bar is at highest point. If you can, swing the pressure foot out of the way or remove it. Ditto the upper blade, if you can swing it up and out of the way to give yourself plenty of clearance.

Then using your small screwdriver, gently turn the needle screw a half turn at a time until the needle is loose and drops out. NEVER undo the screw all the way out, just enough to get the new needle back in.

Most needle bars will hold two needles with two screws so getting both changed is a bit of a fiddle, I usually slide the new needle up into the slot, then hold it up into the housing with my tweezers while I tighten up the screwdriver. Or I'll hold the tip of the needle up in place using a long fingernail while doing up the screw. YOu may find you need to slightly undo the left needle screw in order to replace the right needle as the two needles sit alongside eachother in the housing very closely.

On most sergers the two needles sit at different heights so have a good look before you remove and then make sure you get the new needle back up into the housing all the way. Always test by winding through a stitch manually just to make sure the needle is clearing your loopers afterwards.

You need to re-thread the serger.

Refer to the manual or open the front of the serger to see if the threading diagram is there.

With most sergers, you begin with raising the presser foot, then set the tensions to zero.

Begin the threading with the upper looper (curved looper), then the lower looper and the needles last.

Pull the thread under the presser foot and to the left side of the serger.

Set the tensions back to normal 4 - 5 usually.

Lower the presser foot and hold onto the threas tails as you stitch a chain. If the chain of the four threads is ok, you are ready to serge fabric.

Solution taken from "Handbook for Huskylock Sewing Machine Models 1001L/1000L/1000"

1. Raise the presser foot by using presser foot lever. When the presser foot is raised, the two thread tension discs in the thread tension control panel are released so that thread passes freely between them. Otherwise thread tension may not be correct.

Important! When threading the needle, always be sure to lift the presser foot lever, and also take care to thread in the proper order.

Threading order:
1. Upper looper thread (green)
2. Lower looper thread (blue)
3. Double chain stitch looper thread (purple) in case of 5 thread stitch or double chain stitch
4. Right needle thread (red)
5. Left needle thread or double chain needle thread (yellow)

Caution!
Because the left thread tension dial (yellow) is used for either the left needle or the double chain stitch needle, these needles will never be used at the same time.

Upper looper (green) sequence:
1. Thread holder (silver triangle openings attached to thread holder stand)
2. Thread guide (flat silver clips just behind thread tension disc)
3. Thread tension disc (circular knobs with numbers for tension setting)
4. Pull thread around upper looper guide and upper looper
5. Pull thread into hole of upper looper

Lower looper (blue)
Repeat 1, 2, 3.
4. Pull thread around guide (see color coded chart inside front serger cover).

Easy threading mechanism (for lower looper)
1. Pull out the lower looper threading lever
2. Thread the lower looper and position the thread on hook of the lower looper
threading lever.
3. Push the lower looper threading lever back to its basic position while
holding the end of the thread.

Caution:
When returning the lower looper threading lever, always make sure that the two
blue triangle marks (directional arrows) meet each other.

Right needle thread (red)
Left needle thread (yellow)
Important: Thread the needles after threading of lower looper and upper looper.
First raise the presser foot lever, and then thread the needle threads in order shown in color coded thread guide.
