If no fuel is getting to carburetor, then check the purge bulb located onthe upper right of the engine, in front of the fuel tank.
Keep pressing the purge bulb until you get fuel flowing into the carb.
fuel return line. Also inspect the fuel tank to ensure that the lines in there are not getting clogged with debris from the fuel tank.
Also ensure that this is a fuel problem, and not air or spark problem.
If the problem is none of the above, then you may need to replace the fuel pumping system (primer bulb may be damaged). In that case contact manufacturer to see if parts are available.

Here a thread from somebody with same problem on a sears engine.

To contact Mantis call call. 1-800-366-6268.

Thanks for asking Fixya.

    Replacing the fuel filter for preventive maintenance can
    reduce the risk of dirty fuel causing problems, or a plugged filter causing
    engine performance or starting problems. Some vehicle manufacturers say you
    should replace the fuel filter every 50,000 miles. Others say to replace the
    fuel filter only "as needed," and some make no filter replacement
    recommendations at all.
    Many professional technicians say you should replace the
    fuel filter every couple of years to reduce the risk of a plugged fuel line
    causing driveability or starting problems.

    Replacing the fuel filter can also help extend the life
    of the fuel pump. Why? Because on most fuel injected engines, excess fuel
    pressure from the fuel rail on the engine is routed back to the fuel tank
    through a fuel return line. If the fuel is dirty, abrasive particles can
    recirculate back through the fuel pump again and again accelerating pump wear
    and causing the fuel pump to fail prematurely. EFI fuel pumps can be VERY
    expensive to replace and typically cost $200 to $350 plus several hundred
    dollars labor because the pumps are mounted inside the fuel tank.

    Replacement fuel filters typically cost less than $10 for
    older engines with carburetors, and $15 to $45 for most fuel injected engines,
    except certain Saturn models that cost $90 and are only available from Saturn
    dealers. The oddball Saturn fuel filter contains a fuel pressure regulator and
    is not available from aftermarket suppliers.

My mantis tiller with a honda gx22 engine starts then shuts off after approx. 30 sec.

If your unit has a primer bulb, start your engine . When it starts to die push your primer, if the engine comes back to life you have a carb issue.

Craftsman tiller 5 hp a few years old. can get it to start for a minute or so than it dies. changed plug and cleaned filter what else could it be?

If there are any rubber or vinyl fuel line components it may be time to replace them. I'm experiencing a similar problem with a small "mantis" type tiller and the primer bulb is split. Searching for replacement parts when I came across this post. Hope this helps.

Mantis tiller sv-4 echo engine no spark from coil mantis 2cycle tiller i got it running tryed to start it 4hrs latter same old problem wont start, plug wet with gas wont start. coil was checked by shop...

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
