Thanks txtom50! The link below from your info is excellent. I feel I came close searching but missed this link. Two friends have the need and I have recommended to both they should install their kits. I did about the 80s and gave a Poulan S25 another 10 years (after it locked with a scored piston skirt vs cyl on a 100 degree day). I retired it for parts or rebuild vs throwing a rod after noticing excessive connector rod play this past winter.

Over the years of handling hot saws and a log spliter about a year ago I have started limiting my work in the heat. My goal is to work (at home) in below 70 degree weather or short periods until mild temp is felt on machines (here in TX). I feel this will reduce excessive wear on the machines. Opinions From All !
