Hi,
I pulled my lawn mower out of storage yesterday to use it. I've only ever used premium gas in it but when I started it a lot of white smoke was spitting out of the muffler and it was sputtering. I took the carb off (which I just bought and put on last summer) and cleaned it. Put everything back together, it started up normal and ran normal for a few minutes but then started to intermittently sputter. It progressively got worse and worse and now it barely runs when I get it going and will eventually die. I tried a new spark plug yesterday but that didn't have any effect. What could be going on or where should I begin looking? Thanks.
