Always a little puff of something when I start my 2210, how much smoke and what color depend on the throttle setting, temperature, etc.
I also get the "shut down shuffle" in varying degrees, depending on throttle. Really rattles the bucket when the loader's on, sometimes.
How long you pre-glow the glow plugs can cut down on the smoke, if it's cool out I sometimes glow for up to 5 seconds minimizes smoke.
You might try some Cetane Booster in your fuel, will cut down on the black smoke under heavy load, but not eliminate it.
