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
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?
