Skipping right side stitch on a zigzag stitch, so when i am running a zigzag stitch when the needle goes through the fabric and comes back up it pulls the stitch back with it ??

replace your needle and make sure t is in correctly.

Zigzagging on the raw edge of a lightweight fabric will pull up, because the needle is swinging to the right side off the fabric, bet solution is to use the three step zigzag to overcast the raw edge, it looks like a zigzag mad of dots in the stitch icon. Dont know your model well, but its late model so should have this stitch.

There are several possibilities for skipped stitches. A needle that is dull or bent; using a ball point needle when a sharp should be used, such as a woven fabric, the needle is not all the way up in the needle clamp; the needle was not inserted with the flat side in the correct position (unless your bobbin case is on the side of the machine, that's toward the back), or the top thread and or bobbin thread is not threaded correctly.

If you can grab the hand wheel and move it right and left, then it probably needs a plastic collar that goes next to the left upper shaft bushing.
If not then the cam timing needs to be adjusted.

Skipped stitches
1. The needle is not inserted correctly
Remove needle & reinsert needle( flat side towards the back of machine)
2. The needle is damaged
replace with new needle
3. The wrong size needle is being used
Choose a needle to suit the thread & fabric
4. The foot not attached correctly
Check & attach correctly

Make sure you are using a brand new needle--a dull/damaged needle will skip stitches.

As for the feed dogs, if it is a mechanical machine it's possible the machine is seizing from old dried oil.

Wheel on right side that controls the needle up and down is very tight...

Hello,
Here are a few things to try.

* Raise your feed dogs if your machine has this feature.

* When you start to sew a seam, hold the upper and bobbin thread tails. Hold them back and out of the way as you sew your first couple of stitches. This will keep them from getting caught in your machine.

* Your fabric may require a different needle. Generally, heavier fabrics require larger needles and thinner fabrics, smaller needles. You may also need a larger needle if you're sewing through many layers of fabric. And make sure to use a ballpoint needle for knit fabrics and a sharp needle for woven (or a universal needle for either). And make sure your needle is appropriate for the type of thread you're using.

* Adjust the pressure of your pressure foot, it may be too light for your fabric.

* If your upper thread and bobbin threads are different types, try using the same thread for both. And use a good quality, brand name thread.

* Change your needle plate. Try switching to a needle plate with a smaller hole (a straight stitch needle plate).

Important Note: If you change your needle plate, check to make sure your needle aligns perfectly with this smaller hole before starting to sew. A misaligned needle could hit the plate and break, which could be dangerous. And make sure to change your needle plate back for zigzag and other wide stitches.

I hope this helps.

Hello,
Here are a few things to try. One of these should fix your problem.

* Re-thread your needle
It may be threaded incorrectly (backwards).

* Change your needle
Your needle may be blunt, bent, or otherwise damaged.

* Your fabric may require a different needle. Generally, heavier fabrics require larger needles and
thinner fabrics, smaller needles. You may also need a larger needle if
you’re sewing through many layers of fabric. And make sure to use a ballpoint needle for knit
fabrics and a sharp needle for wovens (or a universal needle for either).
And make sure your needle is appropriate for the type of thread you’re using.

* Adjust the pressure of your pressure foot
It may be too light for your fabric.

* Change your thread
If your upper thread and bobbin threads are different types, try using the same thread for
both. And use a good quality, brand name thread.

* Adjust your thread tension
It may be too tight or too loose.

* Re-thread your machine
It may be threaded incorrectly.

* Change your needle plate
Try switching to a needle plate with a smaller hole (a straight stitch needle plate).

* Reinsert your needle
Make sure it goes all the way into the holder and that it’s positioned correctly – usually with the
flat side away from the bobbin, but consult your machine’s manual to be sure. I know you said you checked this already but it might not hurt to double check it.



Important Note:
After changing your needle plate, check to make sure your needle aligns perfectly with
this smaller hole before starting to sew. A misaligned needle could hit the plate and break, which
could be dangerous. And make sure to change your needle plate back for zigzag and other wide
stitches.
