How is getting two butterflies, drilling holes in them, and if it doesn't work, replacing the originals doing anything wrong? I didn't say to permanently modify a carb he doesn't own. How can you not grasp that? It's a simple modification that can be easily undone. For about 8 dollars at most.

You're trying to stir **** or you have no idea WTF you are talking about.

Either way, step out of the discussion as you have nothing to offer the OP.

Carburetor experience is what I have to offer. Not a bunch of magazine name dropping. Look you can't fix everything every single time. Are you saying there's no way there could be some kind of internal unseen problem in this carburetor? The fact that it could be warped or something like that? These things are generally unlikely I mean you have dealt with enough carburetors to where there was one or two out of every few hundred that just whatever you did you couldn't get to run right. What is your magic unicorn wand work in a different way?

I got to laugh "Holly people" LOL I think either carb works well if it's in good condition. I personally like Edelbrock's cuz they seem less finicky.
now I thought I was pretty damn good at those 1406 s and have a couple myself. I've taken them down to nothing and put them back together with kits and have had great results. But this last 1406 that I had same problem, ran fine but wouldn't idle said the last person that I owned it. I went out bought a brand new rebuild kit and dipped in a vat of carburetor cleaner. Then cleaned every orifice out with spray carburetor cleaner. Then assembled it and it was shining like a brand new penny. Put it on my car and it ran fine like before but could not hold an idle. I sold it at the last swap meet for $60 with the receipt for the $50 rebuild kit and put it out of my life...

If you start "drilling holes" in this highly suspect carb you'll own it...
I suggest NOT...

Understand he's saying he has not paid for the carburetor and if he just takes it back he doesn't have to use it...

Remember as my first comment I posted I'm not opposed to a holly whatsoever and this could be a great test page that it is working great with a Holly just one that's not going to causing headaches out of the gate just for a simple tune like any carburetor will need to be tuned to its motor. Not just have headaches out of the gate.

Agreed... Or your agreeing with me...

I'm recording myself here so you can see I said I many occasions I'm not opposed to a holly. It can be a 1 in 500 carburetor that just no matter what you do has some kind of internal problem. kind of the reason his friend might have just said here give it a try. No strings attached. The gold telling people to start drilling and and find parts for a carburetor that isn't there's no matter how inexpensive it is. I just don't think it's good advice.
If the original poster is married to the idea of definitely having that carburetor at least get a good known running one or a new one and start turning it to his needs. Again that's just comes off the hills of the same exact problem I was having with a carburetor myself. Grant you it wasn't a holly but it was definitely a carburetor I know well.... I definitely agree was upgrading to a bigger carburetor. And of course it's no mystery that I do prefer Edelbrocks. and yes recently one time out of all of the carburetors of the same exact caliber I've tuned and rebuilt I had one finally that was just not worth the trouble.. you can't win them all...
