What causes a lawnmower to get very hot. then hard to start when hot.?

A lawnmower can get very hot due to factors such as inadequate airflow, clogged air filters, or overworking the engine, especially in tall or damp grass. When the engine overheats, it can lead to vapor lock, where the fuel becomes vaporized in the fuel lines, making it difficult for the mower to start when hot. Additionally, worn-out components like spark plugs or oil levels that are too low can contribute to overheating and starting issues. Proper maintenance and ensuring adequate airflow can help prevent these problems.
