New fresh top end, new head,cylinder,piston,rings,head gasket, new ignition,fresh gas,fresh oil, starts and idles but white smoke puffing away at idle and reving the engine, I checked the spark plug, its black, cleaned it up and no help. Is it the new carb I put on with a bad mixture? could it be oil ? I have excellent compression. I was there when the mechanic double checked the rings and the clearance. What should I do? Its a Peace ATV with the ZONGSHEN 250cc
