Oil leaking from air filter area of push mower and mower smoking

Look for a crankcase ventilation tube or such, It may be covered with grass dust and stuff, is probably a sponge to keep dust out of the motor. Rinse it out, and make sure the airway is clear.

Hi Manny First thing is Drain all the oil back out. You have most certainly overfilled it. Try and get as much out as you can from the same place you filled it from. Leave it tilted back until it stops running and then put the mower level for half an hour. Check the oil level now and clean the spark plug and replace it. There will still be oil in the air filter due to over filling. Only put oil in one egg cup at a time until its below max on the dip stick. Run the mower for 20 minutes and burn the smoke off. It may smoke for a few times but thats ok.

oil has either run into the muffler or the air filter assembly clean out and good to go.

Smoke white or blue? = oil overfilled possibly.

QUESTION 1 - WERE YOU MOWING ON A HILL SIDEWAYS IF SO THIS IS THE PROBLEM, IF YOU HAVE A STEEP HILL ALWAYS MOW WITH THE CARBERATOR ON THE UPHILL SIDE THIS WILL STOP THE OIL FROM BEING SUCKED INTO THE CARB.
2 - CHECK THE OIL LEVEL IF IT IS IVER FULL BY EVEN A LITTLE THE ENGINE WILL FLOD THE CARB WITH THE OIL. ONE GOOD THING THOUGH IF IT STARTS TO SMOKE WHILE IT RUNNING IT HELPS KEEP THE MASKITOES DOWN. I HAVE HAD THIS PROBLEM ALSO

Pull air filter see if theres any oil in it,make sure the oil isnt overfilled. Push mowers usually smoke like that if theyre overfilled,or tipped on thier side,if there is oil in filter simply take filter off,drain oil to correct level,and run it till smoke goes away. If none of this is the problem rings are probably shot. Weedeater is a cheap brand and theyre made cheap too,not made to last.

Make sure the engine is not overfilled with oil most of the small rotary mower engines hold about 20 oz of oil.It will push oil out of the breather is the oil level is too high or if the mower was tipped on its side. Also check the air filter to make sure the oil did not saturate it.Once you correct the problem the smoke should clear up.

I have a yardman lawn mower that is two years old. It is now blowing oil out the exhaust and also blue smoke. Any idea what is wrong?

does it turn over slow or fast if it turns slowly thats the problem so it could be battery or starter they have to have a good amount of rpms to burn fuel right when starting if not it floods out the engine with gas hope this helps thanks wade

Black smoke should not be coming from your air filter. If however, the smoke is coming from your exhaust this could be the result of dirt clogging your air filter and starving the engine of air, hence causing the motor to run on a rich fuel/air mix. If this is the case clean or replace the air filter element, and keep it clean. Another reason for black smoke blowing out is dirty oil in the crank case, if the oil is very dark brown to black in color or smells burnt then it needs replacing.
