Hey guys, need some advice if possible. I have an old Husqvarna 137 chainsaw that hasn't been started in over ten years. It's gummed up and won't start, I was bad and let it sit with old fuel. What is the best way to clean out the carb and fuel line to get it going again? We just got nailed with some Nor'easters and I have a few downed trees to cut up.
