I have a Mac chainsaw that acts like the carb is messed up. I've taken it apart but saw nothing that would cause problems. It runs very good when first start up, then boggs and dies. Today it ran the longest so far, about 5 minutes. I have replaced all the fuel lines and filters and primer bulb. I was thinking that if I ran some kind of carb cleaner through it while running it may straighten out. The saw was given to me, and while using it today while it was running so good, I hate to just junk it.
