Lawn Boy 10685 Insight Series 21-Inch 6.5 HP Gas Powered Self-Propelle

So, my lawnmower will start but it only runs a few cycles before dying again. I’m getting white smoke. I’ve replaced the intake and outtake gaskets as well as the carburetor and the breather tube and still nothing. I am only a novice in small engine repair so any insight is appreciated!

Answer this question I have this problem too

Is this a good question?

azabio check and let us know what engine this is. Could be a valve issue....

Not much in the motor to produce white smoke, I would think you may have water in your gas, drain the tank then replace with positive good fuel and you may have solved the white smoke. May take a few starts to pull non bad gas thru the line unless you take the float chamber off and let new gas in.

Good luck
