If the heater is smoking it could be  running to rich,the Bentley book
talks about adjusting this.When you cleaned the heater did you clean the
spark/glow plug? they get dirty and mat not be firing correctly.Also
something the manual doesn't talk about is the points that fire the
spark/glowplug,located on the back of the combustion blower under metal
cover,and there is a set on the front of the blower only open and close
every 33rd revolution which fires the fuel pump.either of these can get
corroded and not fire correctly.But i would check the fuel pump
first,follow the Bentley procedure and then check the spark and points.
