McCulloch manufactures the Eager Beaver line of weed trimmers. All McCulloch trimmers require a fuel mixture that contains gasoline and two-cycle engine oil. McCulloch recommends using a 40:1 ratio of gasoline and oil for optimal engine performance. The best way to mix the fuel mixture is in a gas can. Two-cycle oil containers usually have measurement markings on the side of the container for quick measuring.
Purchase a 1-gallon gas container specifically to store the fuel mixture for your weed trimmer. You can purchase gas cans at gas stations and home improvement centers. Write on the gas can in permanent marker, “Trimmer Fuel” or something similar. This fuel is for your trimmer only.
Fill the gas can with 1 gallon of gasoline. Pour 3.2 ounces of 2-cycle engine oil into the gas can.
Put the gas can lid on and shake the gas can vigorously to mix the oil with the gasoline. Fill your trimmer fuel tank with this fuel mixture only.
Difficult to Start
The incorrect fuel-to-oil ratio will cause your leaf blower to be hard to start. A fuel-to oil-ratio of 40:1 is the best mixture for the Weedeater Featherlite 1500 leaf blower. Fuel that has been pumped more than 30 days is stale and slow to ignite when the engine is cranked; use fresh fuel.
If the carburetor is not adjusted properly or is defective, the leaf blower will be hard to start. Adjust or replace the carburetor as needed. A damaged, dirty or incorrectly adjusted spark plug will also cause difficulties with starting. Replace or clean the spark plug and set the gap to .025 inch.
Does Not Run Smoothly
If your leaf blower lacks power or dies under a load, the problem could be an improperly adjusted carburetor, a dirty or damaged spark plug or a dirty air filter. If the carburetor or throttle is not adjusted correctly, your leaf blower will not idle properly. Adjust the carburetor and throttle as needed, replace or clean the spark plug or replace the air filter to correct these problems.
Too much oil in the fuel will cause your leaf blower to smoke. Empty the fuel tank and refill with fuel and oil at a 40:1 ratio. An incorrectly adjusted carburetor or a dirty air filter will also cause excessive smoke. Adjust the carburetor or replace the air filter as needed.
Turn on the Poulan 2-cycle unit. Allow the engine to idle.
Allow the engine to idle.
Find the idle speed screw located near the unit's primer bulb.
Turn the idle speed screw counterclockwise to decrease the Poulan engine's speed. If the unit is turning or moving while in idle, the speed is too fast.
Adjust the speed by turning the idle speed screw clockwise. If the unit stalls or dies, the speed is too slow.
Locate the idle screw on your leaf blower. Most idle mixture screws are between the air filter housing and the body of the blower.
Start the blower engine, and allow the leaf blower to run at high idle for one minute.
Turn the throttle lever down to the slow position, and allow the leaf blower to idle. If the blower shuts off, turn the idle screw 1/8 turn clockwise with a flathead screwdriver. Start the engine, and allow the engine to idle. Continue turning the idle screw in 1/8 turn increments until the engine idles without shutting off.
Press on the throttle trigger to rev the engine to full operating speed. If the engine hesitates when raising the RPM, turn the idle screw 1/16 turn counterclockwise. Continue making these adjustments until the blower idles and revs up without hesitation.
Start the Craftsman Weedeater as normal following the manufacturer's instructions. Make sure the proper fuel mixture is used in the fuel tank to avoid potential problems.
Allow the Craftsman Weedeater engine to run and warm up sufficiently before making and adjustments. Run the trimmer at a high idle speed by depressing the trigger throttle for one minute.
Release the trigger throttle and observe the operation of the trimmer at low idle speeds. Locate the idle adjustment screw on the back of the Craftsman Weedeater behind the fuel tank. Look for a small hole in the air filter and muffler cover.
Insert a small blade screwdriver into the hole in the air filter and muffler. Turn the adjustment screw to the right or clockwise if the engine is attempting to die at low idle. Turn the screw 1/8 inch at a time until the engine runs smoothly.
Turn the adjustment screw to the left if the engine idle is too fast. Make small 1/8-inch incremental adjustments until the trimmer idles smoothly.
Use a Phillips screwdriver to unscrew the blower's plastic casing on the side with the pull cord. Depending on the Craftsman model, there will be between four and six screws.
Pull the casing off the motor. Directly under the plastic gas tank is a small black hose. Follow it until you see a cylindrical piece protruding from the hose. This is the fuel filter.
Pop the hose off the filter. The filter will come out easily after you take off one side. Remember how the filter is positioned in the hose. Take a new fuel filter and place it where the old filter was.
Snap the plastic casing back on the motor.
Secure the casing by reinserting the screws and tightening them with the Phillips screwdriver.
If your leaf blower is smoking, check to see if it requires a mix of gas and oil to run effectively. The mix could be off. If the blower doesn't use mixed gas, a faulty electrical system or an issue with the motor may be to blame. Take the leaf blower in for repair.
For safe storage you will need an UL listed and FM approved gasoline safety can. These cans will be made from heavy galvanized steel. Important features include:
- galvanized steel construction resistant to physical abuse
- full handle allow easy pouring and carrying heavy load
- positive pressure relief cap vents automatically to prevent rupture or explosion in case of fire
- spring loaded self closing lid prevents spills and controls vapor
- internal flame arrestor prevents flashback ignition
Choose between the type 1 and type 2 safety cans. Type 1 cans have one opening for pouring/filling. Type 2 cans have one spout with a flexible metal hose for filling and a separate opening for filling. Type 1 cans will be less expensive.
Cans should be filled to 95% of capacity. This will allow room for the gasoline to expand due to higher temperatures.
If you plan to store the gasoline for more than a few months you should add a preservative such as Sta-Bil. Add the preservative to the fresh gasoline when the tank is filled. The makers of Sta-Bil state their product will preserve gasoline for 12 months or, if you double the dose, two years. Preservatives will NOT restore spoiled gasoline.
Do not store gasoline in or near the house. The gasoline should be stored in a separate well ventilated area with no electrical equipment or open flames.
Look for the low-speed screw on the carburetor. It is usually marked "L." Turn it all the way counterclockwise so it is embedded in its position. Then turn it one turn clockwise. This is the standard carburetor setting.
Warm up the engine and adjust the idle-speed screw. The idle-speed screw is often labeled "LA." Turn the idle-speed screw clockwise until the chain begins to move. Then turn it back a quarter turn. The chain must not run under idle.
Turn the low-speed screw counterclockwise if the idling is erratic and acceleration is poor -- the setting is too lean.
