When the engine and carb were new, the factory settings were 1 1/4 turns out. As fuel deposits form and things wear, it is normal to need occasional adjustment. If the adjustments need to go more than 2 1/2 turns out, or if the adjustments seem to need constant change, then the carb needs to be overhauled. Here in the USA, many areas use gas that is 10% alcohol. The alcohol effects the soft parts in the carb and will often cause hardening of the diaphragm. If/when you overhaul the carb, also replace the fuel lines and tank grommet.
Good Luck!

Mantis tiller 7222e

Hi anon, if it's starting your 2/3rds of the way there. You have fuel and spark. Try and clean the air filter first and if that fails to keep it running then check that the choke isn't staying out. If all thats ok then it may be the carb gaskets.

Mantis only runs with choke half on.

Try fuel with 30% injector cleaner (or 25% auto transmission fluid) Something is clogging the fuel route.

New coil no spark

more than likely the carburetor jets are plugged up. This is a common thing to happen
the jet is located on the bottom of the float bowl if it is a Techumseh engine
Use a stiff wire to clean through all 4 bore holes of the jets
carb cleaner in a spray can is needed as well

Mantis tiller starts but will not stay running

Carburetor problem. Two stroke engines use oil mixed with gas. Old fuel or setting over the winter will cause varnish and sludge in the Carburetor. Start by buying a can of carburetor cleaner and mixing a new can of fuel.
1) Dump the old fuel and check replace it with new.
2) Remove the air cleaner.
3) Pump the prime bulb 3 or 4 times, set the choke, spray the insides of the carb with the cleaner and then try and start it . It should sputter and run for a few second but chances are it will take a few sprays to clean the jets

MY mantis tiller will start and run for just a few seconds and then it stops. It has new gas and oil in had old gas and oil mis in it but I dumped it all out and got new gas and oil mix....

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.

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.

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.
