Red face 911 new rebuild - rough running with a rattle

Just finished rebuilding my 81 911 SC 3.0 CIS rebuild. Mostly stock with JE Pistons and cat by pass pipe. She started on the second try but runs very rough and backfires. After the 2000 rpm idle period, when I place the engine under a load, I hear a loud rattle, like the engine is lugging.

I have check my plug wires - correct for the SC per Waynes book. I will recheck the static timing before I start it again. It is the rattle that worries me.

Anyone have any thoughts?
