If the mower is dropping out or not starting and you do notice the oil leak, you have a bad gasket. If the mower shuts off when you turn corners, but there is no oil leak, you may still have a bad gasket since the pressure to keep the combustion going is not strong enough.
Will mower run with blown head gasket?
If the head gasket’s seals are weakened or if the gasket head has blown, your lawn mower will fail to operate at full power.
What are the first signs of a blown head gasket?

Because there isn’t enough air, combustion is incomplete, and the unburnt fuel in the combustion chamber turns to smoke. You see the same phenomenon when you burn leaves and pack them too tightly to allow air to circulate.
What does a blown head gasket sounds like?
If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced. This loss of compression results in a rough running engine and a notable reduction in engine power. This sort of failure typically is accompanied by a sound like an exhaust leak.
What happens when head gasket goes?
Typically sitting between your engine block and cylinder head,the head gasket seals the combustion chamber. Driving with a blown head gasket can cause serious problems for any motorist, including; erosion of the engine block, oil contamination and radiator problems which can prove costly.
Where is the head gasket located on a lawn mower?
Locate the Head Assembly These fins may be partially blocked from view by a metal cover stamped with “OHV.” Trace the spark plug wire to the spark plug, which threads into a port milled into the cylinder head. The head gasket is mounted just behind the cylinder head, which is bolted to the engine block.
Where is a head gasket?
Located between the cylinder head and the engine block, you’ll find the head gasket. This small yet vital component is used to seal the internal combustion process allowing coolant and oil to travel throughout the engine to cool and lubricate.
How do I stop my lawn mower from smoking?
Troubleshooting and Fixing the Mower Check and replace the air filter. Check oil level, grade and type. Change the lawn mower oil if necessary. If oil has found its way onto the engine, let the mower run until the oil burns off harmlessly. Checking the angle at which you’re mowing.
Why is my lawnmower sputtering?
Clogged or Dirty Air Filters Dirty air filters are one of the most common reasons lawn mowers sputter.

You want to be sure to clean or replace dirty air filters.
Why is my mower blowing blue smoke?
The mower blows out Blue or White smoke. This is a sign that the engine is burning excess oil. The excess oil in the engine causes incomplete combustion which will create smoke and a carbon buildup.
What happens if you put too much oil in a mower?
Too much oil in your lawn mower may cause the engine to not run well and cause damaging results. Too much oil can cause your engine to overheat which can result in seal damage, blown gaskets or becoming hydrolocked.
How do you fix a Black smoke from a lawn mower?

What are the signs of a cracked head?
If your car is indeed suffering from a cracked cylinder head, you’ll likely notice one or more of the following symptoms: White Smoke (Steam) From the Exhaust Pipe. Low Coolant Level. Engine Overheating. Rough Running and Misfiring. Combustion Gases In the Cooling System. Illuminated Warning Lights. Coolant-Oil Intermix.
Can you hear when a head gasket blown?
If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced. This loss of compression results in a rough running engine and a notable reduction in engine power. This sort of failure typically is accompanied by a sound like an exhaust leak.
Can you smell a blown head gasket?
Smell the radiator (when it’s cool). If the odor is oil, dark or heavy smelling you probably have high back pressure coming through your radiator cap with is another indicator of a head gasket problem. Regularly check the coolant level if you suspect you have a head gasket problem in your car, truck or SUV.

A blown or cracked head gasket can cause one of two problems: It can allow coolant to escape from your engine. The result is a loss in coolant, which can lead to overheating of your engine if you drive it for any length of time.
