at first my top thread was bunching under the bobbin thread so I tightened the tension. Now my stithces are loose between the stitches and it looks terrible. I am using a straight stitch. I have rethreaded the machine, cleaned out the bobbin case, put in a new needle, changed the bobbin thread, and have oiled the machine. Does anyone have any suggestions for me?
In my case, even if I increase the pressure on the lower thread, it doesn't seem to work. There's no pressure at all and it doesn't seem to matter which way I turn the screw....if I pull on the thread there is no tension whatsoever.

bottom thread is loose when sewing a straight stitch
Hello angelee, Go through te process of ellinination even though you may have done it several times, when you thread the machine up make sure the presser foot is up so the thread goes through the tensions discs completely, set the top tension between 4 and 6 that should be ablout right but you may need to adjust it slightly,make sure you have the needle in the correct way round, the bottom tension should be set so you can just pull the thread through with some resistence, if it pulls through too easily just tighten the small screw slightly on the bobbin until you get some tension, if the bobbin is too tight that you really have to pull it through, slacken the screw off slightly, try it an see.
