Why Your Lawn Mower Won’t Start When Hot: Troubleshooting Tips.

A hot engine could cause the spark plug to malfunction, causing a lawn mower to fail to start. A common reason why your lawn mower does not start when it is hot is the impaired air and fuel intake to the engine.

When the engine is already warm, hot air replaces the cool air, resulting in fuel evaporation that can hinder the engine from starting. Sediment build-up in the carburetor, blocked air filters, and faulty ignition system components are the most common causes of hot start problems.

Several troubleshooting techniques can be applied to determine the root cause of the problem and get the engine running again.

Investing in a quality lawn mower from the beginning can also prevent issues in the future. Take care of your equipment, and it will take care of you.
