Question about Mantis 2-Cycle Tiller

Open Question

My tiller was fully serviced by Mantis and a new starter fitted. Its got the correct petrol / oil mix in and a new plug but it will not start. It wants to fire but refuses to 'catch' When this product is working its brilliant but I have always found it difficult to start.

check the fuek lines for hole and leaks, check the fuel filter and clean if necessary. remove the carbuerator and inspect the gasket; it should be soft and flexible, if it seems hard or brittle replace it. clean the carb with carb cleaner sray (available at any local auto parts store) and compressed air. make sure you get inside the small fuel rail holes. check the primer bulb for pin holes and seating/sealed properly. if that doesn't work have the carb repaired at a service center or replaced.

SOURCE: trouble starting old Mantis tiller 9012 - don't have a manuel -

Mantis has the owners manuals in pdf format available for download on its website. The tillers are here (I hope the link to the tiller group works...if not, just go to the main site and look for "owners manuals" link.

Also, you can call a number and get a representative who usually can help at the numbers listed there, find authorized service people if its not something you can do yourself, order parts and find detailed schematics in the owners manuals. My dog actually ate mine. LOL. But they are free, the owners manuals, unlike other places that charge you for them like they were a "part".

SOURCE: mantis tiller sv-4 echo engine no spark from coil

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 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.

Need to know oil / petrol mix for Mantis 2 stoke Tiller


it is a 50:1 gas:oil mix. I'd also strongly recommend adding a fuel stabilizer to the mix, as a tiller has a tendency to sit for long periods without being used. Good luck!

New mantis worked perfectly last season. Stored it for the winter. Tried to start it this spring. Pull cord is frozen up. Can't pull it out.


First, call Mantis and get their advice. It may be covered under warranty (I believe it comes with a 2 year warranty). If not under warranty remove the spark plug and try to pull the starter rope. If you can pull it out squirt a little 2-cycle oil in to the spark plug hole and pull it out several times before reinstalling the plug. Then try to start it again. If you can't pull it out after removing the plug try removing the engine cowl that contains the starter rope and see if you can pull it out then. If you can't then there is something wrong with the starter rope mechanism. Try some oil or Liquid Wrench on the spring to see if you can free it up. If you can then the piston may be seized. Again, squirt a little oil ni the spark plug hole. Take a ratchet wrench and socket to put on the crankshaft nut. Try to turn it. Do not apply to much force. I would send it back to Mantis for repair or replacement unless you are mechanically proficient enought to take the engine apart. If you have been using the correct fuel/oil mixture this should not happen.

How much gas to mix the oil in?


First check that your Mantis needs an oil/gas mixture, most of the newer Mantis tillers have four-stroke motors meaning they have oil in the crankcase and use straight gas. If your Mantis needs oil mixed in the gas use a 50:1 ratio. That's usually 2.6 ounces of two-cycle oil (it's sold in bottles that size) to one gallon of gas but read the oil bottle to get the proper mix ratio.

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

Will not get to working speed


RECOMENDATIONS:

-Drain all fuel from the fuel tank.
-Remove and REPLACE with a NEW spark plug.
-Remove and RELPACE with a NEW Air filter.
-With spark plug and air filter removed and fuel drained pull the starting cord many times 12 or so to ensure there is no fuel in the chamber and also check for a spark at the plug.
-RE-MIX WITH NEW FUEL your 2 cycle oil to the correct ratio in a clean fuel can. it is OK to dump some in the fuel tank slosh around and dump out in an approved container for disposal.
-Hold off on putting back on the air filter until you have had it running

Hope this tip helps.

What is the correct oil/gas mix ratio?


The 2 cycle needs oil and gas mixed while the 4 cycle needs the oil changed every 10 hours of use. 2 cycle is 28:1

Oil smoke on my mantis tiller


Too much oil in the fuel mix. Look for a 2 cycle oil called Opti-2. Comes in 1 or 2 1/2 gallon mix pouches w/fuel stabilizer. One mix for all 2 cycle. It's the best and no measuring, foolproof.
