Stihl 044 had lost most compression and I pulled it apart to find out why. Piston had failed between the rings. I orderd an new piston and installed it. How to change a piston ,clean up cylinder with muriatic acid and assemble. Use baking soda to neutralize the acid then thoroughly rinse.
2 stroke engines are so simple.
Enjoy and comment.
