If you plan on buying something with a small engine on it, stay away from Chondas. After using up a few head gaskets I got from "who the heck knows where", I find I can't buy them anywhere. I called three different, very reliable, parts houses and to get a head gasket, I have to buy an entire kit ($35). If I need a lock nut or a part for the over head valve setup, I have to buy the entire thing. What a crock. There is always folks defending these pieces of junk, and I used to be one of them sometimes. No more, no more, no more, no more. Hit the road Chonda! (More specifically...MTD 139cc imported junk!)
