A clogged fuel filter is most commonly caused by leaving fuel in the leaf blower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the fuel filter and prevent the engine from starting.
A leaf blower works thanks to its electric motor or its gasoline engine. The engine drives the fan`s blades, which rotate at high speed to generate centrifugal force. The centrifugal force acts on the air surrounding the blower and forces it to be sucked into the fan. The fan then pushes the air out of the nozzle.

You can do so by adjusting the idle mixture screws to 1.5-2 turns out, and the idle speed screw to 1-1.5 turns in. Warm the Engine Up. The engine`s running temperature directly correlates with proper air and fuel mixtures.
