Lawnmower spits oil out of the exhaust - What to do?
When out of the blue the mower mashes and smokes, the horror is great for the operator. Often the problem occurs just after a cleaning or maintenance. Why this is the way you act now and prevent it in the future, you can find out here.
How does the oil get into the muffler exhaust?
To protect your health and the environment, gasoline lawn mowers always carry the crankcase breather into the carburetor or intake manifold. If the mower is tilted sharply when cutting grass on embankments or for maintenance, engine oil can run from the crankcase through the carburetor into the intake manifold.
Typical symptoms of the problem are leaking oil from the exhaust as well as a whitish-blue smoldering engine. If a larger amount of engine oil has run into the carburetor, the engine is difficult to start. Instead of air, there is oil in the cylinder, so that the starting process requires a lot of effort.
Cleaning action solves the problem - That's how it works
If your lawnmower spits oil, smokes heavily and is difficult to start, you can solve the problem with a large-scale cleaning. How to do it right:
Perform a test run after this cleaning. If there are no more complaints, you can save yourself the removal and cleaning of the carburettor. If the engine continues to smoke and stutter, do not avoid cleaning the carburettor. Numerous manufacturers offer complete repair kits for this purpose, which contain all necessary spare parts.
Tips
So that no engine oil runs into the exhaust via the carburetor, a lawn mower should always be tilted in the right direction. If it is imperative to lift a gasoline mower sideways, spark plug, air cleaner and carburetor will always face skyward.
