I have requested site to remove the saw for sale. To answer have not opened saw up Ever!! Too few hours to mind that.i know that if you don't use compression release you better be a Very strong man to start it. Have a Great Day and I may take a borescope down the cylinder. Kinda lazy though,still has Original spark plug in it. Gonna ponder on my Saws for a while thank you once again. And yes I am well informed about the qualities of SPs Have had them Since they were first Born! I am an old geezer that loved Trees and Saws and really liked Big Trees and Big Powerful Saws As Well.
