Sorry for the typos. one more question. I read in one of the posts that states when replacing the belts something had to be in the highest position. Please explain thanks again

Hi,. I have aSinger model 111G156 machine. I am not a techician so I am unfamiliar with all of the terminology relating to parts. i just replaced the clutch motor with a Family Servo motor which works fine. the trouble I am having is that the bobbin thread kept knotting arounfpd the bobbin casing. In trying to untangle everything I may have thrown off the timing. Now the needle is not picking up the bobbin thread to pull it up through the feed fogs., therefore, it is not creating a stitch. is there anything I can do to repair it myself since money is a big scarce right now? I have a manual for the 111G155 which I guess is similar to the G156, but since I don't know what the parts are called the manual becomes Greek to me! any advice? thank you Carol
