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: I Have a Mantis tiller that I can get NO spark
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: what is left to do but change the flywheel?
check what they call air gap between the coil and flywheel .010-.012 gap
also be sure your flywheel is in time.
you will actually have to remove it to do this and check for the sheared key or be sure the key way aligns with the crankshaft keyway on the flywheel

Sounds like it's flooding either from over choking or the inlet needle in the carb is leaking. Have you removed the plug and blown out the cylinder and plug with air and then tried to restart? Be careful not to keep cranking with the choke pulled out. When it 'hits' ONE time, move the choke halfway in and crank again
I
also have Mantis tiller for 2 years. From the very beginning I had
a problems. I was referred by Mantis to the repair store and was charged $90.00
for oil drainage. The second time I was waiting for handle replacement for ~ 1
month. This tiller can't handle even little jobs and the warranty doesn't worth
a dime. Maybe I will be more successful using it in my living room . I have an
equipment with Briggs and
Stratton engines and I never had a problem.
To me Mantis mean big advertisement and waste of money.
