hey guys. I bought a replacement 20hp kohler new in september 2005. By the end of October it was using oil like crazy and smoking. I suppose the rings are shot. I took good care of it and it still did this. My question is ... Have any of you had any dealings with kohler and if so, how much trouble will i have getting them to make this motor up? I dont wanna just throw about 1700 down the drain. The warranty is for 2 years. Thanks.
