Just finished the Murray 20" Lawn Mower with the 3.5hp Tecumseh Engine. Runs great, super quiet, not really powerful with a 3.5hp motor, but great for a small yard. Super easy pull start, everything went back together flawlessly. Had a little trouble with the carburetor, some of the old seat was still left and had to clean it out. So I snapped a few pictures and posted it on Craigslist.org for $80, which isn't a bad price for a practically brand new mower. Here's a few pictures of everything dismantled.
