I have a White Model # 12B-959I190 self propelled walk behind mower that smokes badly. It was put away with the old gas in it without any stabilizer in it. When I tried to start it after putting in a new spark plug, it started on the first pull. It seemed to run fair. I let it run for a couple of minutes but didn't sound like it was peaking out and it put out a lot of light blue smoke. When I tried to start it again just a couple of minutes later it wouldn't even pop. I tried a couple of days later and it started on the first pull but ran really ragged and stalled after about a minute. Might it need a carberator cleaning? If that's not it any other ideas? This doesn't belong to me, I'm looking at it for a friend.
