14SH654: Singer 247 Machine runs fine and then bottom bobbi...

First thing--change to a new needle in case it was bent when the threads got tangled. Now un-thread the machine all the way and re-thread it, making sure your thread is going through the needle in the proper direction. You have to have a top thread in order to get the machine to pick up the bottom thread.

Basic Tips for All

1. Always turn the handwheel TOWARDS you (counter clockwise) as turning it in the opposite direction (away from you, clockwise) may knock the timing out requiring repair from a service center.
2. Always be sure your presser foot is in the DOWN position before sewing. Sewing with the presser foot in the up position will cause your thread to tangle and your bobbin to jam.
3. Change needles regularly (after 16 hours of use) as dull/weak needles can cause damage to your machine and fabric. Only use SINGER needles on your SINGER sewing machine.
4. Always be sure you are using the correct bobbin for your machine. Class 66, Class 15 and Class 15J bobbins look very similar. However, using the incorrect bobbin class in your machine can cause damage.

I can't see the take-up lever? wwww

It is most likely the bobbin not right I'll send u a pic also make such it's not in reverse after u insert the bobbin hand turn it one the need will go down and pic up the bobbin thread once it does pull up on needle thread and it will come up with it all way start with bottom and top thread out the back also make sure tension is set or it will wad up

thread bunches up in the bottom of my singer style-o-matic 328k singer sewing machine

I had this same problem yesterday. I took apart the needle tension casing and now it doesn't get tangled or stop. The only thing is the bobbin is not sewing...it looks fine on the top, but the bottom is just loose loops.
