  If your Dolmar Blower engine stops soon after starting, ensure you perform a warm-up operation. Check that the choke lever is set to “OPEN” once the engine is warmed up. Clean a clogged fuel filter or a contaminated/clogged air cleaner. Securely attach a detached throttle wire. For issues related to an abnormal carburetor or drive system, it is recommended to request an inspection and maintenance.
