How can I fix my Pfaff Tipmatic 1151 sewing machine?

The machine belonged to my mother and I wanted to know if there is a way to repair it myself instead of trying to take it to a shop because It will cost me the same to fix it as opposed to getting a new one. The timing is off and there is a part on the the top when I thread the top thread it snags while sewing. I was told that there is a plastic part on it that may need to be replaced because it could be broken.

Any information would be helpful thanks. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
