If your Husqvarna leaf blower won't start when hot, it's likely due to a vapor lock in the fuel system, a faulty ignition coil that malfunctions at high temperatures, or a clogged carburetor that impedes fuel flow. To resolve this, let the blower cool down before attempting a restart. For a long-term solution, check the fuel cap's vent for blockages, test the ignition coil when the blower is hot, and clean or replace the carburetor if it's clogged. Regular maintenance can prevent these issues from recurring.
