A friend gave me a used/neglected riding mower with a 14 hp Briggs and Stratton engine. The engine will start with difficulty, blow smoke and oil out the exhaust, then die after about 8-10 seconds. Seems to run a little longer in the beginning when the engine is cold. Is it worth taking in for repair? The mower is a zero turn Toro with relatively low hours and everything else seems to work fine. Thanks.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Blue or white smoke coming from your engine usually indicates burning oil, which can be caused by: Overfilling the crankcase with oil. Incorrect oil grades. Operating engine at greater than a 15 degree angle.
Oil can come out of the exhaust of your lawn mower when it is tilted to the extreme, especially when the crankcase is overfilled with oil. A clogged air-filter can cause the oil to spill out of the exhaust vent, so simply replace it if this is the case.
This is usually brought on by low fuel octane, oil contamination in the air/fuel charge, or excessive boost or nitrous injection in high-performance engines. It can also be caused by poorly performed repairs, a clogged injector, clogged fuel filter, or a marginally failing fuel pump.
An overfilled crankcase and oversaturated foam air filter will also cause oil to travel from the air filter housing to other parts of the engine. If the mower produces black smoke, then it`s a problem if the lawn mower air filter is soaked in gas. The solution is just to replace the filter.
Too much oil in a lawn mower crankcase causes the vapor released via the ventilation valve to become oil-rich, which clogs the air filter, creating an overly rich air-to-fuel ratio that fouls the spark plugs and causes the engine to smoke and run poorly. Extreme over-oiling will stall the engine.

Oil leaking out on yardman mower – Yard Man YardMan 11A41K3001 21Inch 173cc Kohler OHV Gas Powered BagMulchSide Discharge Lawn Mower (NonCARB Compliant) ()
ANSWER : You haven’t supplied a lot of information but generally when this happens it is due t the mower being tipped the wrong way.
If you must look under the mower then tip it back with the handles to the ground and front wheel in the air.
Now to rectify your problem; The air-filter will probably be saturated with oil. It will probably be the cartridge type which is not serviceable. Purchase a new filter (take your old filter so the sale person can compare like for like). Before you refit the new filter, take out the sparkplug, it will probably be saturated in oil – wash it in petrol, let it dry then refit it. The engine should start and belch out great quantities of smoke. Don’t be alarmed this will burn away. Once the smoke has cleared, check the oil level, fit the air filter and mow your lawn.

Oil coming from line from engine feeding into air
ANSWER : More than likely your air filter is clogged and needs replacing. If that is the situation the carb needs air and is pulling suction on the crankcase breather tube siphoning up oil instead of just burning the vapors. If it was a busted ring the oil would be coming out the exhaust and burning blue smoke.

My yard man mower is blowing black smoke when I crank it. Why would this be?? It was low on oil, but we filled it up and it still smokes. Do we need to change the oil? If so how? It has a honda engine, and is 2 years old.
ANSWER : Like the other guy says drain the oil out. Disconnect the spark plug wire (for safety). Place the mower onto a stable platform to work from. To remove the drain plug usually you need a 3/8 ratchet and I use a short extension so I don’t skin my knuckles. Put the extension end into the drain plug and remove. Have a drain pan to catch the used oil. Clean the area around drain plug first. When oil is drained replace the drain plug and tighten. Add your new oil. ONLY ADD ABOUT 15 OUNCES. Use SAE 30 motor oil. Once you get the oil in set it on a flat surface and check for the proper level. Add if needed. Usually the push mowers only use about 16 ounces. I start with 15 because it is easier to add than remove the oil. Replace the spark plug wire, prime and start. It may smoke awhile to get the old oil burnt up.

I have an early 90’s cub cadet rider and it was over filled with oil. Now it smokes and blows oil out the exhaust. Could over filling it cause this? If not are there any common causes of blowing oil
ANSWER : Yes, over filling can cause this. The fix for this is to put the oil level back to normal, and run your machine normally, until the oil residue burns back off. Some “side effects” may be fouling spark plugs and occasionally residue build up in the muffler, so, keep this in mind. Normally, though, everything goes back to normal. It’s better to run the machine for a while than starting and stopping it, to allow the machine to get up to operating temperature and clean out the exhaust system.
Best regards, –W/D– please feel free to rate this solution.
