YT175 pull start rebuild

[Macs]

Is there any good ways to rebuild one. I have always messed with honda ones and had a very good method. I pulled mine apart to start rebuilding but it looked pretty foreighn in there didnt touch nothing. What is a good method to change the rope in these. On hondas i used a hammer handle to tighten the spring but i am not sure f this method will work.

i am aware of the parts needed but i am looking for a good method. Everyone has there special way of doing these and i need some of those ideas besides ripping my fingers off trying to develop one of my own,
