check the fuek lines for hole and leaks, check the fuel filter and clean if necessary. remove the carbuerator and inspect the gasket; it should be soft and flexible, if it seems hard or brittle replace it. clean the carb with carb cleaner sray (available at any local auto parts store) and compressed air. make sure you get inside the small fuel rail holes. check the primer bulb for pin holes and seating/sealed properly. if that doesn't work have the carb repaired at a service center or replaced.

SOURCE: mantis tiller sv-4 echo engine: no spark from coil

There are only 4 parts to the 2-stroke Mantis ignition system: the spark plug, the "kill button", the flywheel with embedded magnets, and the coil with integral plug wire. There are no "points" to clean or refurbish. If you've tried a new spark plug, unplugged the wire leading up the handlebars, and the magnets on the side of the flywheel are strong enough to attract a screw driver blade, then it must be a bad coil. That's all it could be. End of story.

Cruising the internet I see where these Echo coils go bad all the time. You can order the coil, but if the machine hasn't run in several years the carb will also need cleaning. So one thing leads to another. The gear box grease also needs replacing each year. What I'm trying to tell you is these are disposable tillers and due to length of time, incomplete care/ storage, ....whatever, this one's time is up.

Sorry.

SOURCE: trouble starting old Mantis tiller 9012 - don't have a manuel -

Mantis has the owners manuals in pdf format available for download on its website. The tillers are here (I hope the link to the tiller group works...if not, just go to the main site and look for "owners manuals" link.

Also, you can call a number and get a representative who usually can help at the numbers listed there, find authorized service people if its not something you can do yourself, order parts and find detailed schematics in the owners manuals. My dog actually ate mine. LOL. But they are free, the owners manuals, unlike other places that charge you for them like they were a "part".

set the coil to the thickness of a dollar bill from the flywheel and tell me what happens. make sure kill wire isn't grounding somewhere else

SOURCE: motor run but blades don't
