"Kevin, That doesn't sound too bad. You need to remember that when you are not using the motor, the gasoline will evaporate, leaving the oil behind. You will therefore see more smoke upon startup. In addition, when you cold start the engine burns a richer mixture for a while. the richer mixture also contains more oil, as well as gasoline."

Look for the check valve on the VST (fuel control) At the bottom of that unit there is a fitting that the oil line from that pump (clear tube) connects to the fuel system. That is the piece that goes bad. Every one does it.
