Craftsman 27 CC Weed Whacker & Brush Trimmer
Just picked up a used weed whacker in the title. It runs until it gets hot then shuts down. It has new gas from the pump this morning, clean air filter and runs great at first so I don't necessarily suspect a carb issue. Venting the cap doesn't seem to help.
I'm leaning towards the ignition coil because the primary side resistance seems to change with temperature. When it got hot and died the coil was at 38 ohms. When it was cool it was below 5 if I remember correctly. Is this normal or a bad sign?
