Why does my Echo blower smoke?
A common, simple problem that may cause a leaf blower to smoke is improperly mixed fuel. Gas leaf blowers use a pre-mixed fuel that combines gasoline with a two-stroke engine oil. However, if the fuel mixture is improperly mixed, the fuel will burn poorly inside the cylinder, which may cause the engine to smoke.
Where is the spark arrestor on a Echo blower?
Spark arrestor screens help prevent heated gases from escaping and starting fires. The spark arrestor screen sits inside the muffler on a gas-powered leaf blower. These screens help prevent heated gases from escaping the internal combustion engines.
What causes engine bogging?
The problem of an engine bogging out is commonly caused by inefficiency of fuel or air flow or ignition to the carburetor. If the air filter is clogged or has a lot of dirt in it, it could be bogging down the engine. Clean the air filter and see if the problem goes away.

What is the purpose of a spark arrestor? Spark arrestors are screens that limit the size of particles sometimes found in the exhaust gases of outdoor power equipment.
How does a spark arrestor work?
The most common type of spark arrester will trap carbon particles in the exhaust system. It works by screening the larger carbon particles out of the exhaust. Through centrifugal force, the heavier carbon particles are thrown against the inside walls of the arrester and directed into a trap.
Can you use leaf blower without fuel filter?
Reason 1: A Clogged Fuel Filter That will cause the amount of fuel in the air-to-fuel ratio to be too low.
