A few weeks ago my weed wacker quit running . It was running fine, just stopped. I filled it up with gas ,still wouldn't start. I pulled the plug, it was dry and didn't appear fouled or wet. After playing around with adjustments, it started and would run fine for the next few weeks. Today, I was out doing my thing and it was running fine, then it quit and wouldn't start again. Again I yanked the plug and sandpapered it off, didn't look bad, I pushed the primer bulb several times and appeared to be pushing fuel into the carb as it was coming out the return hose back into the tank. I disassemble the kill button to see it if somehow went bad, couldn't find a problem there. I could test for spark with any certainty as everything would jump around the bench when I pulled the rope. So, Anyone have any other things to try before it goes in the trash. BTW, it's a 2013 craftsman wacker.,,,
