Fuel lines good? How old is it? Was it stored with fuel stabilizer? The typical trimmer cam have old fuel lines that leak, causing engine to lose the fuel and die. The other common problem is the inlet screen in the carburetor plugging with varnish from old gas. Either one of theses can cause it to start and then die. When you prime it do you see a stream of bubbles in the fuel going back to the tank? This is sign of bad fuel line. The fuel lines can be replaced and the carburetor can be cleaned. Let me know. Thank you.
