When ordering parts for your Mantis 2-cycle tiller, you may need to locate the SV number of your engine. The SV number is located between the gas tank & 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.
Examples: SV4A, SV4B1E.

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!
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.

In accordance with current EPA Regulations and CARB requirements, limiter caps have been installed on the high and low screws of the carburetor. Removal of these caps by anyone other than an authorized Mantis dealer will void your warranty.
Replacement carburetor, rebuild kits and gasket/diaphragm kits are available. Please contact us directly.
To order parts, you will need the SV# of the engine.
All cooling fins must be kept clear in order for the engine to operate efficiently.
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 brushNote: 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

Most likely the engine has come unseated properly from the transmission. Check the base of the engine to make sure it is sitting all the way down on the transmission and the gold colored bolt is secure.
Drain out the old fuel and dispose of it properly. Once the fuel tank is empty, push the primer bulb on your tiller 7 or 8 times to clear out any fuel in the carburetor. Empty the fuel tank again. Next, mix fresh fuel in the correct ratio and fill the fuel tank. Push the primer bulb 11 or 12 times to pull the fresh fuel through the carburetor and let the tiller sit for about thirty (30) minutes. Then press the primer bulb an additional 11 to 12 times to flush out any residue. You should now be able to start your tiller using the standard starting procedure.
If parts are needed, they are available factory-direct by calling 1.800.366.6268.
Note: Do not use carburetor cleaner. Doing so will void Echo engine manufacturer warranty.
