Put on a pair of safety glasses. Remove the fuel cap from the Weed Eater and set it aside. Fill the fuel tank with unleaded gasoline that has been mixed with quality 2-stroke oil in a 40:1 ratio. Replace the fuel cap.

Move the Weed Eater to a safe place and lay it flat on the ground. Depress the fuel bulb located beneath the carburetor approximately six times to prime the engine. Press it slowly so that fuel has adequate time to traverse the fuel line.

Slide the handlebar-mounted engine "On/Stop" switch to the "On" position. Slide the choke lever beneath the fuel tank to the "Full" position.

Depress the "Throttle Lock" lever located beside the engine "On/Stop" switch. Keeping the lever depressed, squeeze the throttle trigger. Release the throttle lock. This sequence holds the trigger in the depressed position, which aids in starting the Weed Eater.

Roll the Weed Eater so that it is resting on the engine and the trimmer head shield only. This will allow the spinning trimmer head to avoid contact with the ground. Brace the Weed Eater by holding it to the ground with one hand. Using your other hand, pull the starter rope quickly until the engine begins to run. Do not pull the rope more than a dozen times. If it fails to start by then, squeeze the throttle trigger and continue to pull until the engine starts.

Allow the Weed Eater to warm up for about 15 seconds, then slide the choke lever to the "Off" position. Let the trimmer run for another minute without touching the throttle lever. After the Weed Eater has warmed up, squeeze the throttle trigger once to disengage the throttle lock. The trimmer is now operational.

Hmmmmm. The question is why does it pull hard to begin with? Did the pull cord get wrapped around the pulley in an awkward manner or is the machine seized up? If it's not to difficult, pull the muffler off the machine and look at the piston. If it looks scored (lines up and down the piston through the rings) It's shot and probably not worth fixing. But, If everything looks good, then I'd pull the starter assembly off and see if there's something going on there that's doesn't look right.

hello sir, Please provide the following information so that your issue may be diagnosed properly,what is it? brand name,complete model number The problem, What is happening with what? When it is happening? Are there times it does not happen? Did it just start happening? Did it ever work ? Did any seemingly unrelated event coincide with whatever it is not working? need the model number and brand name, if you need a manual i need the brand name and model number,if it is a riding mower the model number is under the seat.a snow blower the model number is on the rear of the machine, let me know,thank you. ~~ i need to know this before i can give you a answer,,

If it is a pull start, leaving the switch on did no damage to the weed eater.

there is another t20 screw in the neck of the drum. once removed you will expose the drive clutch. soak it good with WD40 then unscrew it from the shaft. if you have all the housing screws out, you should be able to simply remove the housing to expose the pull cord assembly, screwed to housing.

I have a craftman weed eater model M358.796600 and the pull cord will not retract any more...how do you fix it?
