I am a case guy with a jd chopper. My
question is will the 619cid engine always
smoke enough to smoke out the birds in
the machine shed? When it warms up its
fine bit when it's started wow lots of
smoke. I had the injector pump rebuilt
and new injectors. Are those engines
always like that?
 
Some engines are like that. The white smoke is unburnt fuel. a cold engine that is getting low on compression is notorious for that. If it still runs and starts good. Don't worry. Just run it.
 
Aneroid comes to mind. Thought they were supposed to help starting, but help limit smoke. Maybe Dieseltech or others will chime in. You might put out a call to him on the forum.

The purpose of aneroid to to limit fuel rate when throttle is shoved open, until the turbo catches up.

On the "619", there's a mechanism that disconnects it to allow full fuel rate for better starting.

Once it starts, and the governor grabs the "rack" to limit speed, it's connected back up, but will have no effect on fuel rate at a speed and load it would likely be running at while in the building.

The aneroid is NOT the problem here.

Those engines have a relatively low compression ratio for a diesel, because once under load, turbo boost makes up for that, and WILL smoke at idle when not warmed up.
