I bought a Honda 21" Mower for trimming and tight spots about a month ago at one of the Orange Big Box stores I'm sorry to say. It ran great for about 3 weeks. After that I had major problems starting it after it got hot. So yesterday I brought it back and swapped for a new one. Bring it home and decided to cut my grass for a change. Thought I would try it out. Well guess what. It ran like a champ for about 10 minutes then started sputtering and stalled. Let it sit for 5 minutes and tried it again. Same thing happened. Am I doing someting wrong here or am I just having bad luck?
