    I have the singer 758 and the thread is not catching the bobbin thread.  The hook moves but doesn't catch the thread.

When you turn the handwheel, does the hook move? If not the top gear on the vertical shaft is stripped and needs to be replaced.

Singer 6235 - needle not grabbing bobbin thread

Make sure of 4 things. One, that the correct needle length and diameter is being use in the machine. Second, make sure you are turning the flywheel the correct direction and third, and fourth, that you have the Bobbin inserted correctly and spinning in the right direction. when picking up bobbin thread.

I have recently bought Singer Quantum 9940 and I am not happy with the stitch. For zigzag stitch, I can see too much of the upper thread on the bottom side. This happens unequally: more on the right hand...

1. Make sure your needle is correct for the fabric. Go buy some good needles in several sizes. You'll need a 90 for jeans, rounded points for fine fabrics... get a few sizes. Your manual should provided you with clues to the right needle for the fabrics. (BTW... there really is no such thing as a Universal Needle... toss it.)

2. Re-read your manual and carefully follow the instructions on threading the bobbin and the upper thread...

3. Check your tension on the upper thread... it is too loose for the application. The tension on the bottom thread is handled by a spring on your bobbin case or race. If you do not have that threaded properly you'll have problems. Same with the direction the bobbin turns... have in it backwards... problems.

Barring all these things... It might be time for a qualified Singer repair person to look at it. Sadly Singer has seriously lowered it's standards in the last 20 years.

The needle hits the plate and doesn't go down to grab the bobbin thread reguardles of the needle position.

Sounds like a timing issue, Unfortunately it is not a do it yourself job. You need special tools and the training to do it right. Sorry, but you are going to have it serviced.
