Just fired up the mower...its been about a month or so since I've started it. I did put sta-bil in the tank. When I started it, it poured thick smoke, but only for about 5 seconds. Any reason why? Any thoughts would be appreciated. Thanks!
That's normal for the first exhaust to be smoke. My diesel does that. I think it's because as it sits, a little of the fuel flows from the lines into the cylinder chamber and makes the first ignition a richer fuel which smokes due to incomplete combustion. Posted via Mobile Device
Ran it for maybe 5-10mins when I first stored it, just put in the regular 87 octane. Same gas from when I first stored it. It was white smoke, but nobody tipped it, I'm the only operator of this machine. Posted via Mobile Device
It is common for an engine to put out a little white smoke after
being stored, and the cause is usually condensation embedded in
the metal around the valve chambers and cylinder chambers, not
often is it oil or water in the fuel line or tanks as others have said.
