Our own Muv also has a video about tensions
How to adjust the Tension on a Vintage Long Bobbin Sewing Machine - 1934 Singer 128K Indian Star

If you are NOT into video and want some instructions here is good information - a bit more details than the video as well. http://www.tfsr.org/pub/technical_in...echanism_2.pdf

Thanks so much!! I can't get the link to Muv's video to come up, it says there is an error on the page?

http://www.youtube.com/user/Muvandfa.../5/S43_-Z6C114 see if this works better for Muv's video on tensions. Her other videos are excellent as well. Grab some tea and enjoy.

Here is a bit more info - not video though:

I have a picture of how a Japanese 15 should look threaded but it won't load on here, sigh.
If it is not threaded through the tension right - it won't work. Thread has to go across the machine, through the tension, through the spring then up over the tension bar (if it has one), through the take up lever and on down through what ever thread guides then into the needle from the left. The needle has to go in according to the manual.

Try checking the pressure regulator on the top of the machine above the pressure foot.
