MECH-NO-POWER
Craftsman · Craftsman B210 27cc 2-Cycle Gas Leaf Blower (210 MPH)
The blower engine runs but produces significantly less air velocity/volume than normal. The Craftsman B210 is rated at 210 MPH air velocity. If output seems weak: (1) Clogged air intake — debris, leaves, or a dirty air filter restricts air entering the impeller. Check and clean both the engine air filter and the impeller intake area. (2) Worn impeller — the plastic fan/impeller inside the blower housing can crack, chip, or have blades break off, reducing airflow. Inspect the impeller through the intake for damage. Replace if damaged. (3) Leaking blower housing — cracks in the blower housing or a loose housing gasket allow air to escape before being directed through the nozzle. Check for cracks and ensure the housing is assembled tightly. (4) Engine not reaching full RPM — a dirty carburetor, clogged exhaust/spark arrestor, or dirty air filter prevents the engine from reaching full speed. The impeller airflow is directly proportional to engine RPM. (5) Clogged nozzle — debris may be lodged inside the blower tube or nozzle. Remove the tube and check for blockage.
