    yea you need to take the carb apart and inspect it and clean it. mabey a gasket is bad. where is it leaking from on the carb? the gas is supposed to go trhu the carb and shott into the engine on top of piston( which it isnt getting to enginez0

    I'm fairly sure that the problem is due to some gunge from the fuel tank either jamming the float valve down so's it "thinks" there's no fuel in the tank, or else there's a hole appeared in the float, and that's what's holding it down.

    The problem now is :- are you sufficiently skilled to take the carburrettor to pieces?

Mantis tiller won't start

Flush out old gas. Check/clean spark plug. Oil filled? Try spraying starter fluid in carb. Carb should not have any oil in it. Change air filter.

Mantis tiller will not start. Cannot get primer bulb to draw fuel.I replaced all of the lines,primer bulb still won't work. Tiller will start by priming cylinder by removing spark plug. Help?

Make sure there are no leaks in the bulb. Did you reattach the fuel lijnes correctly? You should feel resistance after pushing 3 or 4 times to ensure fuel is getting to the carb. If necessary replace the bulb. Otherwise check with Mantis at or give them a call for troubleshooting assistance.

most carb problems can be remedied with a carb. kit & cleaning.
However, this problem is solved by replacing the carb. 95% of the time.
not exactly what you wanted to hear.

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

Mantis tiller 2 cycle seemed as if it was running out of gas

Check fuel filter and lines, if thay are good I would get a carb kit and set the adjustment screws at 1 turn out from lightley seated to start. Don't lean high speed screw too much.
You might check muffler & cylinder port for carbon first.
