How do you stop vaporlock in a stihl chainsaw?

To stop vapor lock in a Stihl chainsaw, ensure that the fuel tank is filled with fresh, properly mixed fuel, as stale fuel can contribute to vapor lock. Check for any blockages in the fuel lines and clean the fuel filter if necessary. Additionally, running the chainsaw in cooler conditions or allowing it to cool down periodically can help prevent vapor lock. If the issue persists, consider inspecting the fuel system for any defects or leaks.
