How do I start the McCulloch MAC BVM 165 Blower?
To start the McCulloch MAC BVM 165 Blower, make sure the blower is on a flat surface. Set the choke lever to the "Start" position, press the primer bulb several times until fuel is visible, pull the starter rope sharply until the engine fires, and then move the choke to the "Run" position.
What should I do if the blower won't start?
If the blower won't start, check the fuel level and ensure it's fresh. Verify that the spark plug is clean and properly connected. Also, check the air filter for clogs and ensure the choke is set correctly.
How often should I clean the air filter?
Clean the air filter after every 5 hours of use or more frequently if operating in dusty conditions. Remove the filter, wash it in warm soapy water, rinse it thoroughly, and let it dry completely before reinstalling.
What is the correct fuel mixture for the blower?
The McCulloch MAC BVM 165 Blower requires a fuel mixture of 40:1, which means mixing 3.2 ounces of 2-cycle engine oil with 1 gallon of unleaded gasoline.
How can I troubleshoot a blower that has low power?
If the blower has low power, check the air filter and spark plug for dirt or wear. Ensure the fuel is fresh and correctly mixed. Inspect the exhaust port and muffler for carbon build-up and clean if necessary.
How do I maintain the spark plug?
Inspect the spark plug every 25 hours of use. Clean off any carbon deposits with a wire brush and check the gap, ensuring it is set to 0.6 mm (0.024 inch). Replace the spark plug if it is worn or damaged.
What should I do if the blower vibrates excessively?
Excessive vibration can be caused by loose parts, imbalanced impeller, or debris lodged in the blower. Check and tighten any loose screws or bolts, inspect the impeller, and remove any debris.

Before storing the blower, empty the fuel tank and run the engine until it stops. Clean the exterior and air filter, inspect for any damage, and store it in a dry, cool place away from direct sunlight and moisture.
What safety precautions should I take when using the blower?
Always wear protective gear, including goggles, ear protection, and gloves. Ensure bystanders and pets are at a safe distance. Avoid loose clothing and keep hair tied back to prevent entanglement.
How do I change the blower's impeller?
To change the impeller, first ensure the blower is off and the spark plug wire is disconnected. Remove the blower's housing screws to access the impeller. Unscrew the impeller nut, replace the impeller, and reassemble everything in reverse order.
