Yesterday, while mowing, the engine slowly died (according to my worker) and then would not restart. This morning, I checked it and the engine turns over but shows no sign of ignition of fuel. I checked the fuel line from tank and it is open and flowing fuel. A piece of debris about an inch long and diameter of a toothpick flowed out of the fuel sediment bowl inlet. I assumed that this may be causing an obstruction. I checked the fuel in sediment bowl and it was clean, with no debris, etc. in bowl. Reassembled and attempted to start. Now, on turning over, it tries to run for a second or two then dies. Next step?
