runs rich at first start up.

[AllenEM]

My bosses M1009 went you first start it in the morning or if it has sat all day start up and it seem like it 's running a little rich compared to mine. his smokes (black) and smells like a lot of unburnt diesel. mine smokes to but its more gray smoke. any ideals why his would be that rich. oh and he has to use his glow plugs every time he starts his. Mine I can go out 2 hours or so and mine will start without using the glow plugs. We both have push button PG's

Check the cold starton the pump. It should increase idle when cold.

 

[AllenEM]

the high idle does work. It's just when it starts that first 5 seconds

His may be turned up.

 

[AllenEM]

then would it be rich all the time not just at start up?

Diesel running rich? hmm correct me if wrong here guys.. but a diesel does not have any intake butterflies or anything to control air flow.. Its wide open.. how the RMP is controlled is by fuel amount only. So if it were running rich the rpm would go up. I mean just my 2 cents here. You might want to think of other things why its blowing black smoke like a stuck injector, worn oil seals on the valves that leak oil down in to the cylinder while it is sitting and you get that burning off.. oil control rings.....also retarded timing can cause a smokey start up/running.

If your smelling fuel on start up, I would individually test your Glow Plugs. I suspect you have one or more that are not functioning.

How is his airfilter?

[FONT=&quot]There is a lot of smoke at stare up, but it is misty white or blue smoke. I first thought it to the usual valve stem seals being bad causing oil to drain in the cylinders while sitting for a period of time, but it has the smell of raw fuel very strong. I was confused by the fact that it seems to be so rich it smells like raw fuel but the smoke is not the black smoke you would associate with that.[/FONT]

I had some black smoke and apparently had a leaking injector, eventually hydro locked engine which caused the starter nose to break, I had the starter rebuilt. After the excess fuel leaked down the engine would start. I had the injectors rebuilt and she ran great only problem is white smoke from the left exhaust and looseing coolant so apparently I blew a head gasket.

 

[T_F_E]

if it is white smoke I would assume a glow plug is bad.

whats blue smoke mean ?

 

[Blood_of_Tyrants]

Blue smoke is burnt engine oil. You have bad piston rings.

 

[mistaken1]

How is his airfilter?

ditto

 

[Cucvnut]

i never said i had blue smoke. i just asked what i meant. bad piston rings would = while smoke
