Tuff one. When a machine sits for a long time the deisel will go bad. First drain the tank and put fresh diesel in it. Or you can get some conditioner at any truck shop. Black smoke means not enough air. Look for a rats nest or leaves ect, in the burner The valves in the pump will stick from the minerals in the water. This will cause your hose to pulsate and your pressure to drop. See the 6 brass caps? There are 3 on the top of the pump head and 3 on the front bottom portion of the head. Hotsy uses an Allen that is 9/16. Remove the caps and you will find the check valves in there. Remove them clean them and put them back in. Make sure the o-rings are still good before you put them back in. Put the caps back on and try it again.

Karosene is not as good it does not atomize as well. Sounds like you have a soot problem or an air flow problem in the burner. Check the output side of the coils where the flame comes out for soot buildup. It is black like ashes but darker. It will plug up the air passage in the coils. You can use air to blow it out or you could stick the end of the wand in there (with the burner shut off of coarse) and wash it out. Check out the insullation inside of the burner, sometimes it will fall down over the fuel nozzle assembly.
