We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
The spark arrestor is a small screen that prevents the engine from emitting sparks. Over time, the spark arrestor can become clogged with soot. If the spark arrestor is clogged, the engine may stall. To unclog the spark arrestor, remove it and clean it with a wire brush.
A: The fuel-oil mixture ratio is 40:1. You can obtain this ratio by mixing 3.2 oz. of two cycle air cooled engine oil with one gallon of regular gas. Over a period of time oil will separate from gasoline.
There may be old or bad fuel in the carburetor float bowl. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and make the engine hard to start. If the carburetor is clogged, try cleaning it with carburetor cleaner.
Sometimes the spark arrestor screen can become clogged up itself. Common symptoms include lack of power, especially under load; poor acceleration; engine won`t come up to full RPM; and higher than normal “spit back” through the carburetor.
The fuel filter might be clogged. A clogged fuel filter is most commonly caused by leaving old fuel in the leaf blower. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog the fuel filter and cause the engine to stall.
These screens help prevent heated gases from escaping the internal combustion engines. In many countries, these screens are a mandatory requirement for not just all leaf blowers, but most internal combustion engines, such as cars, motorcycles, chainsaws and other lawn and garden equipment.
