My son was driving home last week when he lost all power. The exhaust was belching smoke. I towed him home and suspected a cylinder head gasket but on draining an overfilled sump discovered a oil/fuel mixture. I renewed oil and started car. It ran ok for a few minutes but then quickly developed same symptoms. The sump had again filled with fuel. Do I have a problem with my fuel system, automatic choke or perhaps carburettor float ?
