  1. In the era while B&D was buying Craftsman I purchased from a Sears Store (March 2017) a Craftsman rear tine tiller. Is it quite likely this Zongshen GB210 is the engine on that tiller? I can see on the engine a numerical engraving and I can see a label with a lot number and a serial number, however, I haven’t seen anything identifying the manufacturer or model.
