Ok, so here is what I have so far. The #6 header tube about 1 inch from where it leaves the head has a 1.5-2 inch long crack in it, basically right at a bend. Using my official tool (old heater core hose) I have determined this was my "tapping noise" I heard. Even without using the hose, I can still hear it if I listen closely. I also found my header bolts needed some tightening as well.

I use to be able to hear my mech fuel pump before all this happened. Now I am having a hard time hearing its pumping noise. I am half wondering if it is going bad on me, so I may need to put my new carter pump on it. I am trying to hold off til I get a fuel pressure gauge and regulator mounted in the line, which nobody around here has in stock.

Oddly enough, when I try to adjust the idle/air mixture screw, the driver's side will kill the engine if I take it all the way in (about 1.5 turns). The passenger side however, can be closed all the way in and barely if any effects the idle of the car. Ok, so now I know I have a blockage. I also found that if I shoot carb cleaner in the primary idle air bleed (inside the choke horn area) for the passenger side, it made the idle speed up a little. Shooting it in the driver's side one made the idle die down and stumble.

The timing is at 12 degrees, set with both the timing light and a Vacuum gauge. Setting the timing anywhere else right now and it doesn’t run worth a crap. I also noticed my idle is now up to about 1,000-1100 rpms. I tried to get it back down under that where it normally would be, but it just wants to die then.

I am going out to yank the carb, try to clean it out and get it back on before work tonight at 7.

What is everyone' opinion on the headers? They were on the car when I bought it (full length) when it had a c-4. When I put the AOD in it, I had to heat them up near the collector and "tweak" them so they would clear my AOD. I can’t find anyone that makes full length for this combo. Should I get another set and tweak them, or just get a good set of shorty's?
