Husqvarna in particular. Friend has owned a Husky for a few years which ran fine for about a year and then started dying after it got warm and refused to start again. He took it to the local saw shop(den of thieves)and it has had the carb rebuilt, the carb replaced(although I bet it was just doused with brake clean and never replaced), all new filters and plug(twice). Never worked right-same problem. In passing the other day he asked if I wanted it. Not really, but I took a look at the innards. It is very awkward for me to start a saw now as I have to stand with my foot in the handle and in a peculiar motion I can do it left handed. Yes, there IS a chain brake! So I wanted to be sure things were in order before I attempted this feat. Popped the recoil side cover off and discovered the entire flywheel/ignition module was packed with fine cutting dust and bar oil. The magnetic pickup/transfer point on the module was covered with a glaze of slime reducing the open part to about half the size of a pencil eraser. I removed about a dixie cup full of gook, cleaned everything with alcohol, set the gap between flywheel and ignition module. Started on first pull and he has been using it for a few days now-no problems. The saw shop in question NEVER bothered to check the main ignition parts. So before you give up on late model saws, check the simple stuff first. I can only guess at what this outfit charged him-for nothing.
