Edelbrock 1406 whistling

Thanks for the safety tip, Stroker...it's the only thing I had on hand; I hope not to blow myself up (we country boys do some dumb things, sometimes)! :iconbigg:


Thoughts?
Rob

Hey Rob,
Welcome to FABO.
I usually try to stay away from tech advise due to so many more here with more mechanical knowledge than me.
But you asked for thoughts and as many here know, those don't cost me nothin so I share when asked.:coffee2:
I have some experience with that carb on BOF (our old 67) had a 318 with about your same set up. So here's what I had goin on.....

I think you have proven to me you have a leak around the shaft. Just my thought after seeing vid.
YES, I too (Hoosier Hollar dwellar) use carb cleaner for leak checks, SO WHAT! Anyway....
That carb is real sensitive to cross stress or "pulling" on the linkage by not setting square or any other above average stress on shafts. It took me many trys to get all linkage adjusted to operate smoothly with no cross stress or too much retun spring tension.
I'm just sayin'!
Our eddy 600 would whistle like a turbo on a semi when heavy on the petal with all 4 open going up a hill all through second and third gears (Auto) untill it planed out and secondaries closed down.
It would give all kinds of weird symptoms of illness when not installed as recomended on instalation video on website.
I'm back country hollar bumpkin hoosier boy and would never tell someone you should or tell how to spend money.
Watch the vid at the eddy website for instalation in their tech section. Link;

Start with Vic's intro!
They recommend a certain MOPAR style spacer under carb with 4 directional holes in it not the spread bore and not no spacer at all. Also recommend larger diameter air cleaner after total carb rebuild.
Ours would never run properly untill we followed the install vid to the letter, then we had no problems from that carb again. That was just what happened to us though.

Disclaimer;
ONLY meant as a representation of what I was thinking at the moment (My thoughts per your request) and not meant as an expert should of comment, I am not a mechanic! I did not mean any disrespect or ill will of airing my thoughts, ie my 2 cents worth is all it's worth!

Good Luck and keep us posted.
John.:cool:
