After about 3 snows it started running poorly. Took it to the MTD authorized service center and they diagnosed a bad carburetor.
Parts were supposedly ordered but I never got to use it again that year as the parts never came in until June. Leaked oil when got it home and still ran poorly so I took it back and they decided that it need a new engine. Months later I got it back again and the engine did run ok but it never ran straight down the sidewalk and did a really poor job of removing the snow.
Very unhappy with this machine. Definately do NOT recommend.
Monetary Loss: $379.
