Your Lawnmower in the Winter

In the winter, gasoline evaporates faster than in the summer because of lower temperatures and humidity. This makes gasoline harder to burn, which is why it coats the insides of the carburetor, combustion chamber and throttle body with varnish-like sludge.

The carburetor, combustion chamber and engine are coated inside with this sludge which then prevents the spark plug from working correctly. The engine will still run but it will not produce optimal power levels. 

When it is colder outside, moisture can condense on the insides of the fuel system. This causes the flow to be restricted, which in turn impedes fuel performance and increases engine wear. 

In winter, we are more likely to have water buildup on our lawnmowers due to condensation that occurs because of cold weather or fuel restrictions caused by moisture. 

Fuel will get sluggishly through restricted passages and will cause increased engine wear.
