Unhappy Smoke comes from oil furnace after shutdown

Hi, I have a oil furnace in a mobile home, it has the Beckett burner, and when the burn cycle ends smoke comes from the combustion chamber. Does anyone know why?

After drip

The smoke is caused by fuel dripping from the nozzle after shut down. Now comes the tough part (the cause of the after drip): Air in the fuel system; Incorrect 'Z' dimension; cracked heat exchanger; furnace needs cleaning; bad fuel pump, & the list goes on...

Call a heating professional thats familiar with Coleman or Miller Mobile home furnaces.

These are not toys the consumer can work on....your life may depend upon it.
