Edelbrock 1406 whistling

YOU AIN'T GONNA BELIEVE THIS......I figured it out.

ALL of it.

The Whistle.

The missing.

Everything.

And it makes me look like a big dumb, asshole.

I discovered it by pure accident this afternoon, when I was chugging home from work. My brakes suddenly "went", and after a bit of panic-induced pedal stomping, I pulled over to see that hell ELSE was wrong.

I figured the booster vacuum line was loose, so I opened the hood to check. No, the line was still hooked up, and the engine was still running rough and whistling, but I noticed the booster fitting was missing a rubber boot on one of the big nipples. A-HA! I put my finger over it, and the car ran smoother, but was still whistling. I picked up a wood stick for a plug and prepared to fix the problem so I could get it home.

THEN I SAW IT.

I don't know how in the hell I missed it before, but when I grabbed the booster fitting to twist it around to put the stick in, my fingers fell across a third vacuum fitting lurking on the back, bottom side of the fitting...my hand closed around it, and the car smoothed out perfectly.

BINGO.

The top of a gol-darned vacuum cap had apparently rotted off, leaving that @#!*%i-ng nipple to whistle like a mo-fo...I could NOT believe it.

All those carb gaskets. All those plates. All this intake gaskets. All those times I pulled that damn Edelbrock off that car to try and stop it from whistling, and it was that frikkin' booster nipple THE WHOLE TIME.

I now feel like a TOTAL DUMB ***. I guess you live and learn from this kind of crap, but I'm just flabbergasted at my oversight. Oh well, I've got some new parts now.

I want to thank everyone who contributed to solving this issue...I almost wished it had not been such a stupid fix (for a stupid, Captain Obvious mechanic like myself), but I appreciate all the help.

You guys rock. :thumblef:

Case closed.
