Hi everyone..i have a Craftsman LT1000 Lawn Tractor (Model #917.272670) w/17.5 briggs & stratton IC OHV & i just went out to mow the grass & when i fired up my rider it started a little ruff & after i put it in gear it sputtered really bad & almost died & then it picked back up spewing out a ton of white smoke & got back up to high idle speed then about 30 seconds later it did it again then got back up high idle speed & kept doin it over & over until i turned it off...i checked the air filter (which was filthy) & cleaned it & checked the oil (it was a little low but not that low) & tried again & it did the same thing. any help would be greatly appreciated

Listen Dumbass, I always wanted to say that. How old is the gas? You may just want to change the plug. Make sure you check and gap the plug.

You don't say how old this machine is and whether it has been maintained. Any and all information can be important.

Sounds like your battery may have an internal short or wiring to battery may be shorting to ground. I would first check wiring and make sure that it is not exposed somewhere causing a short. You can take your battery to most Auto Parts stores to have it checked out for free. Hope this helps. :smile:

Howdy dumbass,

White smoke is excess water and/or moisture in the combustion process. Black smoke is too much fuel (rich condition). Blue smoke is oil.

I have seen with my own eyes a ton of white smoke coming out the exhaust and causing the same engine running problem you are experiencing from a riding lawnmower caused by the float needle being stuck open and filling the crankcase with gasoline while the engine is off. The oil/gasoline mix, much to my amazement, will burn white and look like exhaust from cars on cold wintery days. However, in your case you mentioned that the oil was actually low but does the oil smell like gasoline????? If the oil smells like gasoline you need to stop and change the oil before attempting to start the engine or you could do a lot of damage to the engine, but before do that, you need to shut off the fuel supply to the carburetor and fix the float/needle valve problem

Is it possible that the color you thought was white is actually a bluish-white smoke? To me, this would make more sense, since the oil is low, that the engine is burning oil and that is the cause of the smoke. What do you think, dumbass?

Wow! I also own an LT1000 that does the exact same thing! It's my wifes mower and she fusses about it evertime it happens, and I don't know what to do about it. It doesn't do it every time tho. I always said it was white smoke too. It seems to do it as she engages the PTO most of the time. It will sputter and cough and spray a plume of smoke and then clears up. I used to think it was because my mower shed has a slight grade to it and I was parking it with the engine downhill. But now that I back it in the shed it still does it, but maybe not as often. Mine is about the same age as the other Dumbass mower. :laughing:

I'm going to replace it soon anyway so I'm not all that concerned, unless it's a simple fix. Wifey always has something else to fuss about anyway:rolleyes:
