93 smoke with 99% biodiesel

My buddy's 93 (club cab/chassis, 4x4, 4.10, 80+gal fuel tank, stock engine/inj pump) smokes on soy biodiesel, he says especially at 2000+rpms, even at opterating temp. Runs "normally" on #2…Air filter looks clean…Why the smoke? Any thoughts appreciated. (Also posting in 1st gen. forum)
