When the trigger is pressed and the throttle is increased on a backpack blower, a metal wire pulls open a vent on the carburetor, allowing more fuel into the passages. The increase in fuel translates into an increase in engine speed. If the throttle is stalling, a problem is occurring in the fuel delivery system and an insufficient amount of fuel is reaching the carburetor to power the engine. This problem often occurs in conjunction with the use of bad, old or poorly mixed gas. If you think leaf blower stalls when i give it gas then read our below guide.
Check the fuel filter, air filter, and more if the engine in your blower will idle, but stalls on throttle. For a list of more parts and to better identify the problem with your blower, follow our repair guide. This is a general guide for your repair; for more detailed information on your model, refer to the owner’s manual.
Unscrew the cap on the backpack leaf blower’s fuel tank. Drain any gas that was mixed more than one week ago from the fuel tank into the approved fuel container. Scrub the walls of the tank with the brush and rag.
Pull the pickup nozzle and attached fuel up into the tank opening with the metal hook. Pull the pickup nozzle off the end of the fuel line. Replace the pickup nozzle if it’s dirty or the screen is clogged. Insert the new pickup nozzle into the end of the fuel line. Set them back into the bottom of the fuel tank.
Unscrew or unhook the air filter cover. Pull the air filter pad from the filter box. Wash the air filter in water soapy with dish detergent. Rinse it under cool water and give it one night to dry thoroughly. Reinstall the air filter and cover to the engine.
Mix a fresh batch of leaf blower fuel. Pour the two-stroke engine oil and regular unleaded gasoline into the approved fuel container. Combine them using the mix ratio provided with your model’s fuel specifications. Shake the gas and oil of blower for one minute before putting it into the fuel tank.
Start the backpack blower’s engine and allow it to warm up for at least 10 minutes. Find the three carburetor adjusting screws on the side of the carburetor. Insert a small screwdriver onto the idle speed screw, which is often set apart from the high- and low-speed screws.
Rotate the idle speed screw clockwise until the blower starts blowing on its own. Turn the idle speed counterclockwise again until the blower stops. Rotate the screw clockwise again to the highest engine speed before the blower starts working.
Insert the small screwdriver onto the low-speed adjusting screw, often marked with an “L.” Turn the screwdriver clockwise until the engine produces a higher-pitched surging sound. Stop turning the screw and move it counterclockwise until you hear a bubbling sound from the engine.
Move the low-speed screw between these two extremes to find the cleanest, smoothest engine sound. Fine-tune until the engine sounds its best. Depress the trigger and check the acceleration of the engine. Increase the low-speed screw 1/8 turn clockwise if it’s still sluggish. Readjust the idle speed in the same manner once the low speed is set.
Why Does my Leaf Blower keeps Stalling?
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the leaf blower for a long period of time. This sticky fuel can clog the fuel filter and cause the engine to stall. If old fuel was left in the leaf blower, drain the old fuel from the fuel tank and replace the fuel filter.
Why is my Echo Leaf Blower Losing Power?
The air filter may be clogged or dirty. If the air filter is clogged, the engine will get too much fuel and not enough air. As a result, the engine may stall. If the air filter is clogged, replace it.
How do you Clean the Carburetor on a Leaf Blower?
After successfully removing a carburetor from the leaf blower, cleaning follows. An aerosol carburetor cleaner should be used to clean the carburetor. All the ports and jets located on the carburetor have to be thoroughly cleaned. Cleaning has to be done for several minutes to get good results. Afterwards, the carburetor should be allowed enough time to dry. Drying is done using a clean rag. This should take not less than 10 minutes. It is crucial to dry the carburetor well to avoid damage to its diaphragms. The damage is likely to occur depending on the carburetor cleaner used. The damage occurs if the carburetor is reconstructed before it completely dries out. Compressed air is also used in cleaning a carburetor. It is used to remove the cleaner that remains on a carburetor.
How do you Clean the Air Filter on a Leaf Blower?
The air filter is found in a filter housing that is (usually) on the back of the blower near the carburetor and the fuel tank. The casing is usually held in place by either a locking nut or using the clips found on the case (these are the most common two locking devices, refer to manufacturer guide if you see anything different). Remove the casing, then remove the old air filter and put the new one in it’s place. Then reinstall the outer casing. That was easy!
