Why will my mantis tiller not start?

SOURCE: Mantis 2-stroke tiller won't start

This could be one of several problems...
• Last year's fuel. Get some fresh gas.
• Every 2-stroke needs a new spark plug each year... you know what that means.
• Clogged carb jets due to storing the tiller over the winter with fuel in the system. Never, ever do that. Now you'll need to pull the carb apart and clean it. Most of the orifices are so tiny you can't see them. Good luck.
• Engine is so old the crankshaft seals have hardened with age. This is one reason no 2-stroke lasts longer than about 8 years. If the seals are shot, then it will cost more to fix than a new one costs. Time to toss it.

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

did it also run out of oil, because it seized like it did you might of burnt the engine

you probably have gum or varnish built up inside the carb. take it apart and clean all the ports and jets with fresh gas. drain the float bowl and fill it with fresh gas as well. if you are not familiar with carbs, best not take it apart yourself, or pay VERY close attention to how it came apart.
