How to Diagnose & Repair a Weed Trimmer that Won't Start or Run. This weed eater trimmer came in and the owner wasn't sure what was wrong with it but said it would not start or run. In this video I will walk you through the process I took to diagnose and fix the problem it had. In the end it had a fuel problem because the fuel lines were rotten and leaking and fuel was not getting to the carburetor. You will see how to install new fuel lines, a new fuel filter and adjusting the carburetor so this string trimmer will run at peak performance. #husqvarna #weedtrimmer #stringtrimmer #stringtrimmerrepair #smallenginerepair Some of the Tools I Use: ✅ Brush Cutter Blade kit: https://amzn.to/4mr9QsD ✅ Hex head bits for impact: https://amzn.to/4jYQWrX ✅ Torx Bit set for Impact: https://amzn.to/4mjF5Gv ✅ Surgical Hemostats 10" long: https://amzn.to/4dvAw8c ✅ Carburetor Adjusting Tools for 2 cycle carbs: https://amzn.to/4kkSr3p ✅ Torx "T" handle set: https://amzn.to/44DEXeJ ✅ Hex "L" Key Wrench set Metric & SEA: https://amzn.to/4kp8GwC ✅ Spark Tester: https://amzn.to/4mp81gw ✅ Endoscope Camera to check piston and cylinder wall: https://amzn.to/45drE4H ✅ Compression Test Kit: https://amzn.to/4j6kWRm ✅ Digital Multimeter Tester: https://amzn.to/45bBfco ✅ Universal Trimmer Head: https://amzn.to/4ko95iP ✅ Brush Cutter Blade Kit (assorted): https://amzn.to/4j3NY43 ✅ Fuel Line for 2 Cycle Engines: https://amzn.to/4khknVW ✅ Red Armor 2 Cycle Oil: https://amzn.to/3UCuD0n ✅ Fuel Stabilizer: https://amzn.to/41i5FqR ✅ Plastic Welding Kit: https://amzn.to/3GZIeer ✅ Upgraded Plastic Welding Kit: https://amzn.to/45kNe7o As an Amazon Associate I earn from qualifying purchases. *If this video was a help to you give it a "thumbs up".
