My lawn mower works for awhile, starts to sputter but still works and then no longer works. I have brand new gas, there is a lot of stabil in it, and the tank looks clean. I have replaced the spark plug. Any suggestions?
My suggestion is to state the brand and model of the motor next time you ask a motor-specific question.

I had a mower that did that. Turned out to be a fair amount of water in the bottom of the carburetor bowl. Some mowers have carbs with bowls and some don't. Mine was a Sears brand, don't recall the brand of the engine it used. It must have had some water in the gas tank too as it did the same thing the next time I used it. Solution was the same, drain the bowl. Was ok after that.
I had a problem with my lawn tractor; it would only run when the choke was out. I posted here recently and there were many good suggestions on what to try. Turns out the fuel shut-off solenoid was bad; don't know if your engi ne has that on it, but that's a last resort.
add a little 2% or so alcohol to dissove any possible water in the gas.
I suggest that you write a post which tells us the make, model, horse power, type and brand of engine, how long is "for a while", and what you have tried so far. . Christopher A. Young Learn more about Jesus

pure 100% alcohol, at about 2% of the volume of gas it is added to.

Might make it 12%

For small tanks that are easy to drain and bowls that are easy to remove, just drain the old gas.
Now if it was a car or truck, the alcohol would be easier.

And acetone would be better (water is soluable in acetone).
I just did that and it didn't seem like there was a lot of water in the gas. I'll try to run it today to see if that works before taking it in. Thanks for the assist.
100% pure alcohol does not exist "in the wild" and is pretty hard to buy anywhere.
The carb bowl did not do any good after all. As per usual, it started, I was able to mow for about 10 minutes, it sputtered for about another minute and then shut down entirely. IT is a 139 cc PowerMore engine on an MTD self-propelled mower. Only about 2.5 years old.

Any water is too much water!!!!
