Bad gas can do it but a sniff can tell. If it smells like turpentine, it's bad. Your may also have a plugged syphon tube (inside the tank).

Why does yardworks 173cc bs engine will start, run, for 2-3 seconds then stop

Bad gas. Drain gas and refill with fresh gas with Stabil. Old oil. Drain oil fill with fresh 30w oil, 16-18oz. Clean air filter and spark plug.. Relpace air filter if dirty. Saving $$$ on this simple tune up is not intelligent.

I 1050 will run fine for about three minutes and then cut off. When i restart the engine starts hunting and running rough. have replaced carb and fuel pump. cub cadet brand

sounds like the gas is bad, drain tank, refill will known good gas. You may want to put a fuel cleaner in with the gas, if you let equipment sit around for awhile with gas in it it will tarnish and draw moisture. Hope this helps Tim

4 1/2 HP B&S motor on lawn mower. Starts and runs fine for a minute or so. Then it begins to "hunt" ie: to surge and drop off and surge and drop off, blowing black smoke as it does this. The air vane...

You should check the vacu jet carb on this mower for either a vacuum leak where it mounts to the gas tank, a blocked or split intake tube in the the gas tank or a weak/worn out diaphragm.

You can spray a little carb cleaner at the base of the carb while its hunting and see if it smooths out. If it does you have a warp between the carb and tank. Either the tank is bowed or the carb *(nowadays made of plastic) is not flat anymore.

You can either buy a new carb or gently sand the warped one a little and see if that works.

Be sure to take pictures of your carb setup before removing it so you can reassemble later.

Governor hunts

Pour vinigar and hot pepper sparkles into the gas tank and mix it with the gas. Then start it- the differance in the way it runs will be very noticable!

I have an onan 18 hp twin cylinder (early 90's vintage) that replaced the koehler in my JD 318 tractor, it seems to surge at anything but maximum power i.e. revs up and down all by itself even though...

Hunting & surging usually is the carb. main fuel jet is dirty, restricted fuel passage, or the governor. Try running some Seafoam carb cleaner through the gas tank first and see if it helps, and don't use ethanol-blended fuel. It absorbs moisture.

Weedeater lawn mower shuts off, but still has 3/4 tank of gas

On some mowers...if the gas cap vent is not working properly, it will run fine for about 15 or 20 minutes, start spitting and sputtering, if you loosen the cap, and let air back into the tank it starts running normally again.
