Sears 20" chainsaw starts won't stay running...Help!
I have seen all the messages regarding chainsaws that start but don't stay running. I am in the same boat. I have a sears 20 inch chainsaw (358 351200). I have replaced all of the fuel lines, the fuel filter, the spark plug and have installed a brand new walbro carburetor. The chain saw starts, idles smoothly and will run at high speed initially. Once the chain saw gets up to speed, it will die after about 20 seconds. I am able to start the saw again after choking and pulling 2 or 3 strokes, but the same thing happens. I have gapped the plug, cleaned the air filter, changed the fuel and am at wit's end. Any recommendations?
