I've been adjusting the alda on my 84 TDT for months, trying to get a balance of power and white smoke reduction. If I turn the alda screw cw to eliminate smoke it loses too much low-end power. The present setting (@ 1 1/2 turns from wide open) provides power but constant white smoke idling and under load, whether I'm burning dinodiesel or biodiesel.

Is there another adjustment/fix I can make in addition to the alda to solve this problem?

Happy holidays

White smoke?

or do you mean grey smoke.. hard to distinguish the too.. sometimes..

white smoke is burning coolant/water

grey/black is excess fuel

What's your Coolant temperature when running?? White smoke can be caused by a cold diesel engine......

It's gray smoke. Engine temp is 90C.

About the only time I see a smokeless diesel is when it's not running.

If you have smoke at idle, the ALDA is not the problem. You probably either have a severe air restriction or you are burning coolent.
