Bottom thread is not being picked up, I hit a straight pin, changed needle, and cleaned it and checked, the timing seems to off how do I set the timing

Sounds like the top thread is not picking up the bobbin thread. If so, be sure to install a brand new needle & check that it is installed facing the correct direction. If it still will not pick up the bobbin thread, then most likely the machine is out of time (which happens easily when the needle hits a pin, a dense seam, or even the needle plate or presser foot). Search for sewing machine timing or take it for service.

Do you have the bobbin in correctly? Clockwise or counterclockwise...
Is the needle in correctly? It could be backwards.
Rethread the bobbin if the thread is not wound on properly...too fast makes the thread too tight, too slow and it can wrap onto the bobbin in a haphazard way.
Check to be sure have the correct needle for your machine...matches stitch etc..
If your machine is electronic...turn it off so it goes back to any default settings.
seems like a lot, but one little thing...

when the needle breaks on a pin that can cause a
problem with the timing, the machine needs to be serviced

check the needle to make sure that it's inserted correctly, the flat side of the needle goes to the back of the machine,, and make sure the needle goes all the way up into the needle cavity .

make sure the bobbin is correctly inserted

clean under the needle plate area & in bobbin area for loose threads or lint

if none of the above work & the needle is still hitting something then it 's a great possibility it's out of time & needs to be serviced, cause the needle should not be hitting anything when it goes down.

Remove the needle plate and the bobbin case.

Ensure that the needle is inserted all the way up into the needle clamp.

Set the machine for straight stitch, center needle position.

Slowly turn the handwheel in the normal sewing direction and observe the following hook timing setting:

When the needle reaches it's lowest point and travels up 3.5mm, the point of the hook should be directly behind the needle, or at least within 1 or 2mm.

Another view is as the hook passes the needle, it should pass the needle slightly above the eye of the needle.

If the timing looks good, use some alcohol on a bit of cloth to clean the hook, careful around the tip of the hook as it is very sharp.

If the hook timing is off, you will need to take it to a knowledgeable service person as there are several possible solutions and several other related adjustments which will need to be made.

Hello,
Here are several things to try.

* When you insert your new needle, make sure it’s positioned correctly (usually with the flat side away from the bobbin, but consult your manual), that it goes all the way into the holder, and that the screw is securely tightened.


If there doesn’t seem to be a problem with your needle, try the following:

* Check your pressure foot and make sure it’s attached securely.


* Change your pressure foot Your pressure foot may be bent, causing your needle to hit it.


* Don’t sew over pins a needle that hits a pin can break. Always remove the pins from your fabric before they reach your needle.


* Don’t pull your fabric as you sew. You could be bending your needle back, causing it to hit your needle plate instead of going into the hole. Just guide your fabric, letting it feed on its own.


* Check your needle plate and make sure it's securely in position.


* Change your needle plate. If you’ve been using a straight stitch needle plate (a plate with a small hole, often used for sewing fine, delicate fabrics), switch to a needle plate with a wider hole.


* Check the position of your needle. Sewing machines with zigzag capability allow you to adjust the position of your needle – right, left, or center. If your needle is not positioned correctly, it may be hitting your needle plate or pressure foot.


* Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your
bobbin case. Re-thread your machine, reinsert and re-thread your bobbin.

* Change your bobbin. There could be a nick along the edge of your bobbin spool that’s catching your thread as you sew.

Also, before 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.

I hope these solutions help you.

it sounds like no bobbin thread tension. there should be some resistance when you pull on the bobbin thread. if there is none or too little you may have some lint or thread caught behind the bobbin case tension spring.

very carefully try and push the tip of a thin pin into the bobbin case tension spring and pick any accumulated thread or lint out.

if the bobbin case spring is clean, try tightening the bobbin tension a little at a time until your zig zag looks ok.

of-course all this is done after checking needle threading and needle for damage.

indicates the needle hook timing is off and the hook is penetrating the thread instead of picking it up cleanly
make sure that the needle is in correctly with the thread groove facing the right way

Because it is almost a straight stitch but the needle continues to move in a zig zag fashion is reason to believe it is in a long stitch. By changing the number of stitches per inch there will be a very noticeable looking zig zag stitch.
