[ATTACH=CONFIG]522242[/ATTACH]I have a 158.19410. I think I bought mine in the early 80's.
I wonder if your button that can be switched from the red dot to the white dot has the handle broken off. Here is a picture of my machine. It needs to be oiled and cleaned because it hasn't been used since 2001 when I got my new Kenmore. I also have another Kenmore that was given to us as a wedding gift by my parents in 1973. I have tried getting it out of the cabinet also but gave up. I need to see if I can get that one cleaned/oiled also. I will check the spring mechanism on that for you. The cabinet sits at the end of my sewing desk and is used to hold my small design board and helps with the weight/clumsiness of bigger quilts.
