Model No. 247.88780, bought in Jan. 18'2011, it will run at choke then once I start to slide the lever to run, engine dies out (very sensitive). I have cleaned and open the carburetor, seems that it runs out of fuel or air cutting the engine off. Do I need just buy a complete carburetor. assembly and change everything or open it again soak it in cleaner over night?

A complete replacement carburetor will just buy you another set of parts identical to the ones you already have. Nothing is worn out.

You should be able to clean the carburetor inside with SPRAY carburetor & fuel injector cleaner, after opening it up. Spray the cleaner through the jet and every passage you can find. Be careful about your eyes - some passages lead back toward your face, and carburetor cleaner is NO good for your eyes!

When it's clean, examine it to be absolutely sure everything's assembled correctly, especially the float valve ("needle and seat"). Put it back together and reinstall it on the engine.

Put a little FRESH gasoline (NEVER use old gasoline in an engine!) in the tank.

Now take off the fuel line (from the carburetor) and make sure fuel drains from it freely. Put it back on immediately and loosen the bowl. Fuel should also drain from the bowl freely.

Last, doublecheck your idle mix adjustment screw. If you toyed with it, you have to get it adjusted correctly again - a good starting point is SNUG (never TIGHT), then back it out counterclockwise about 1-1/2 turns. Once you get the engine started and running without the choke, it (the screw) should be adjusted until it's very slightly rich (counterclockwise) from the point where idle speed drops if you turn it clockwise any further. Said another way... get it idling without the choke, then turn that screw in (clockwise) 1/4-turn at a time until you can hear the idle speed drop. At that point, back it out (counterclockwise) about 1/4 turn.

If you CAN'T get it to idle without the choke, then just try backing out (counterclockwise) that screw 1/4-turn at a time. Each 1/4-turn should make it run just a little richer, necessitating less choke.

Starting procedure

Terry: According to

  • 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.

    Automatic choke will not shut off once the engine is running so engine dies. Could it be a spring is missing ?

    There is a diaphram that the link connects to the choke. It is between the carb and the gas tank, and runs by the vacuum from the engine. B&S engines have to rev up for the choke to open all the way.

    I have a sears 247 889571 24" snow blower. Start fine. Runs rough, like the choke is on. Choke is off. Fresh gas (ran it dry last spring). Ran 1 tank through with it running very rough. Just as it ran out...

    You ran it dry at some point. Gas tanks collect crud and water at the bottom over time and this may have been sucked up into the fuel filter or carb. Clean or replace fuel filter, then remove and carefully strip apart and clean all parts of the carb be gentle with brass and any moving parts in the carb, clean with plastic tools.

    I start the engine and it sputters at fast idle and then eventually shuts off.

    I think that after you start the engine you need to move the throttle lever off what you are calling fast idle (which is full choke). Simply slide the throttle lever down until it smooths out and runs properly.

    I bought a Sears edger #536 796526. It dies on me.

    Hi Tom. You are not doing anything wrong. That being said, your edger has a slightly gummed up carbeurator. I would go to an auto parts store and get a can of a product called seafoam. this is a gasoline additive. Add one ounce per gallon of gas and use this as the fuel for your edger. You will solve your problem in just a few minutes after using this product, I believe. Give it a try and let me know.
