Kohler engine smokes upon starting?

Kohler 23 HP twin cylinder engine on my John Deere Lawn tractor blows blue smoke upon starting, then clears but still spews a little blue smoke afterward. Possible problem? What to check and in what order?

    sounds like valve seals oil getting buy wile it sets then burns off when started they are just rubber seals that go around the valve stem.

    Mine does that too if I park it with the front of the engine downhill. Over the 25 hour oil change period I use none to very little oil so I choose to ignore it. Valve seals might solve the problem.

    OIL needs to be changed or the weight is too light for the age of the engine !
