The fact that you have oil coming out of the muffler and getting on the manifold tells me that the engine is running very cool Also you say the smoke is white. That sounds more like water than oil. A good portion of the exhaust from the engine is water vapor. If the engine is idling with no load and does not have a functioning thermostat it is quite likely what you are seeing is water mixed with soot from combustion. This is usually more often seen on diesels but it is possible for it to happen on gas engines too. If you have only been running the engine under no load for as long as you said you probably have sparkplugs starting to foul out from soot deposits. With todays fuels you should be using Champion D18Y rather than the original D15Y plugs. If you are not using the tractor for any heavy work you may have to go to D21 plugs. Do not use D21s if you are going to be using it for heavy work as they will cause preignition problems. If you want to use a brand other than Champion, just cross those numbers to which every brand you like.
