Singer 301 won't stitch properly, thread bunching up on underside
Likely that it is a lower tension issue
Bottom tension is controlled by the bobbin case. First, ensure that the thread is wound tight onto the bobbin (should not be spongy when you push your fingernail into into it) Looking at the open side of the bobbin case, insert the bobbin into the bobbin case (so the thread winds off in a clockwise direction) and feed under the 'tension finger'. If you now hold the end of the thread, suspending the bobbin and case from it, the assembly should not drag any more thread out of the bobbin case. If it does, the small screw on the tension finger needs to be tightened slightly. If the assembly does not drag out any more thread, give the thread a little upwards tug. The assembly should slide down a little.If it does not slide, the tension finger is too tight - loosen it a little.
Insert a NEW needle, make sure the top thread is correctly threaded and tension is set at the 'normal' setting (as per book) ..... .... try sewing a sample. Note: using 'cheap' thread will cause all sorts of tension issues as well as fluff up your machine fast - avoid it!
