I'm looking at the Exmark Metro 21" mower. I've ran the old 2 cycle Toro's, but they are gone and I need backups. What do you guys prefer, Kawasaki or Honda engines? I know honda's run great but I've heard that they can be gutless? Also BBC, any comments? Is the honda engine worth the extra money, or does the Kawasaki run as good and as long?? Thanks a lot, and have a great spring!!!!!
