How to check or replace the fuel strainer
Here's how to check or replace the Fuel Strainer.
The fuel strainer allows a steady flow of clean fuel to go to the carburetor by straining out any sediment that has entered the fuel tank. It is located inside the fuel tank and can be accessed by removing the fuel tank lid and pulling out the fuel line through the fill hole.
The strainer should be changed whenever it is hard to the touch or creases to allow fuel to reach the carburetor.
Stale fuel will shorten the life of the fuel strainer!
How to check or replace the spark plug
Here's how to check or replace the Spark Plug.
NGK and Champion spark plugs are the only recommended spark plugs to be utilized in Echo engines. The use of the correct type, brand, and heat range of a spark plug is of paramount importance in today's emission certified engines. Never uses spark plug manufacturers cross-reference charts. Cross-reference charts are approximations and may recommend spark plugs that are as much as 1-2 heat ranges out of the recommended heat range.
The plug will depend upon the SV number of your engine; the gap will be the same for each engine - .024-.028.
The SV number of your engine is located between the gas tank and the carburetor, behind the gas line, on a black and silver tab on the silver engine housing. It will consist of the letters "SV," a number and another letter. Sample: SV4A, SV4B1E.
| Engine | NGK | Champion (Equivalent) | SV5C1 | BPM8Y | CJ6Y |

Muffler screen and spark arrestor information
The Muffler Screen is also known as the Spark Arrestor. It is a small screen layered within the muffler system in accordance with current EPA requirements. This screen is in place to catch all burned off carbon deposits.
By virtue of the parts function, it can get clogged with the same carbon deposits it is created to catch. Once clogged, the screen must be cleaned or replaced for efficient operation of the engine.
Do not clean Spark Arrestor with anything flammable!
If your engine bogs down under a full load, your muffler screen (spark arrestor) may be clogged and not allowing the engine to breathe properly.
Additionally, if you find the starter rope hard to pull, it could be because the muffler screen (spark arrestor) is clogged.
Directions for cleaning the muffler screen for your specific engine can be found in your owner's manual. Here are some basic instructions:
- Lift engine off of the transmission by loosening the brass colored screw located at the base
of the clutch case. - Remove the spark plug.
- Remove the red cylinder cover.
- Remove the muffler cap.
- The muffler screen (spark arrestor) will be layered beneath the muffler cap
- Clean or replace the muffler screen (spark arrestor) with carburetor cleaner, using a soft brush
Note: If the screen remains plugged after attempts at cleaning it, it must be replaced - Reassemble the muffler, the cylinder cover, and replace the engine onto the transmission
