Why would my lawn mower be running bad at a high altitude?

Answer by  slickytfox (235)

Check the blade and the deck. Often times a stick or a rock may get jammed and prevent the cord from retractiong. Flip the lawnmower over, while not running, and remove any object that may have got stuck there.

There is a problem in the mix of oxygen with fuel (assuming it's a gas mower and not electric). You will need to adjust the carburetor to correct the mix. If it's an electric mower, the problem is that the armature in the motor is wearing out and needs to be rewound.

If you are at a high altitude the air contains less oxygen and ( I am assuming you have a gasoline motor)the mix is not right for motor is run correctly. Check your manual for the proper setting.

Most likely it is running poorly due to the lack of oxygen at high altitude. In order to fix this you should have your carburetor adjusted for high altitude operation.

The air pressure is lower at high altitudes, and this may have some effect on the engine. The low air pressure is what causes a balloon to pop when it flies to high altitudes. Weather balloons expand in flight because of the air pressure - maybe the engine is effected similarly.
