I have a fresh 4.1 alloy head that has suddenly begun to run rough at idle and is sluggish on acceleration.
Placing figers accross the primary on the weber, almost blocking it(choking), settles the motor to correct idle, very smooth.
I have rebult the weber, twice, timing is correct, no obvious vacuum leaks.
Any thoughts??

Sounds like you might have a valve not seating properly.
