Mantis 4 cycle (brand new): oil leaking out, smoking soaking air cleaner, quits running..

Oil is leaking out and soaking foam air cleaner and dripping onto machine, smokes alot when under a load, runs for 15-20 minutes, then quits. what type of oil should be used? how much oil capacity? where can i purchase owners manual. thanks jt in illinois It's not necessarily worn out, because mine is doing the exact same thing (except that it doesn't quit) - and mine is brand new!. Oil leaks out on the right-hand side, dripping onto the "fender". This is associated with a lot of smoking and low power. Then it clears up and runs OK. Perhaps I have overfilled the oil? I had used the machine for a few hours (they filled the oil where I bought it), checked the oil, and thought perhaps it could use a little - only put a small amount in, but that is when this dripping started. Hope someone can help.

    The first part of that last post was by "jt in Illinois", who was having a similar problem. Somehow it got appended to my post. Sorry!

    Hi Jim!

    Thanks for your input and sorry for my delay in replying. Actually, my machine was not prone to stalling, but it was smoking, boggling, and oil was dripping out of it. I took it to the store where I bought it, and they found the oil reservoir had been overfilled by the technician who assembled it.

    All is well now. Thanks again!

Sounds like your gas tank is not breathing properly. try this: the next time you run the tiller and it begins to stall out, try loosening the gas cap. It should start running again. This means that the gas cap is clogged. Unclog it or purchase another one.

I added to much oil it leaked out of the carb now when I strat it up it smokes white smoke for a minute then stops and runs fine

If you are concerned, you can remove some of the oil. Place a pan under the mower and loosen the oil pan bolt but do not remove it completely. Drain a few ounces of oil out and then tighten it up. Be sure to take the wire off the spark plug before you do this. The lower oil level should stop the smoking.

Hard to start and oil soaked air filter, smokes and loses power

It sounds like it got tilted on its side. The air filter needs to be cleaned or replaced and the carburetor needs to be removed and cleaned.

When the tiller gets tipped over toward the air filter, oil will run out into the filter and the carburetor.

If the filter is foam you can clean it with gasoline, if its paper just buy a new one.

The carburetor is between the air filter box and the engine, it should come off with a few bolts, just remember where the springs hook up.

Open it up, take it apart and spray everything with carburetor cleaner from your local auto parts store. When you put it all together it will run like new!

Mantis starts and runs but lacks power and is slow to rev up

Check the air filter and ensure it is clean, replace if necessary.Foam filters can be washed in hot water and detergent, paper filters need to be replaced.
Ensure the throttle cable moves freely and the choke is turned off after starting.

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

White smoke honda mantis rototiller

You're okay the white smoke is the oil burning off the muffler. In time it will stop, just park it somewhere and let it run until it's done. If the problem persists check your air filter and make sure it's not stained with oil, if so you can wash the foam part with soap and water but the paper will need to be replaced. (DO not put foam back on unit until dry.) The oil level should be up to the bottom lip of the dipstick access when the engine is evenly horizontal.

Oil In the air filter

Back pressure. You will need to tear into the mantis and replace all the gaskets. You can do it the cheaper way by going to Kragen and just buy a tube of gasket sealent, or you can go to mantis and order the rebuild kit. I recommend the gasket sealent for me that has always worked better
