the spout gives electronic timing advance to the distributor... short for spark out... thats why you didnt have power when driving with it out. the tfi module on the distributor does have a tendency to fail, but my experience is that it just shut off and wouldnt fire. and if it did was random at best... didnt cause idle issues. i'm still leaning towards vacuum leaks... there are alot of lines that are hidden in wire looms and such. a thing to check as well is the fuel vapor lines between the charcoal can, tank, and intake. there is a valve that controls flow in the engine compartment.
