I think I need to go to Carter BBD Skool !

I've never claimed to be the brightest bulb in the knife drawer, but this is getting ridiculous, even for me.

I wrote that novel in the first post out of desperation, looking for what I missed. My parts guy says, "It's going to be something really simple." Me, "Is not!" My buddy that helped build my tube headers says, "The only thing that can make a carb whistle is a vacuum leak." Me, "Don't got one. I triple checked."

My buddy takes a can of starting fluid, soaks the throttle shaft where the shop attached the one-barrel linkage and there's the vacuum leak.

I triple checked everywhere for vacuum leaks EXCEPT where the highest recommended carb guru did his work. I chat with the carb shop next.

Man, stupid hurts. :BangHead:
