Re: 1969 L46 throttle bracket

Do these have the part numbers stamped on them? Mine has a Capitol "N" only.

I don't think that any of these brackets have a GM part number stamped on them. The "N" is likely a manufacturer's ID mark.

Thank You Sir.

I as well have the 207 carb; but mine has a funny little bracket bolted on the hole above where you have your cable stud and or in the hole where the incorrect BW photo has his stud. Did you have the bracket and remove it? Mine is suppose to be an NOS to the person I bought it from and the bracket looks like it might be a stock piece.

Also, any idea what the lower ball stud is on your carb? The 207 is for a manual if memory serves me correct; not to mention there would be no detents on an M40.

No, I sure don't. My engine builder said he thought my carb as a service replacement. But the numbers I ran were correct and the date code was in line so that's as far as I researched it.

Mine almost looks like a different base than the Dobbins photo. What do I need to do to make this correct? Just remove the Ball Stud?

Going by what I know about Pontiacs; as well the star head screws on the top cover would not be correct for 69. Yes I would take the extra stud off; I don't see how it could apply to a Corvette since they didn't have the M38.

I don't know for sure what this 207 replacement carb supposedly all fit on; or when they were produced, but I was told by the guy I got it from mine was taken out of the GM by him as NOS. I was just curious what the bracket was for; I don't see how it could provide a function cruise or otherwise, I'll shoot a pic of it.

MUCH to my surprise I found what is prossibly my original throttle bracket to my car last night in the car; I don't see an N or anything on it. If it wasn't so dang hot down here I would get out in the blast shed and clean it up for close inspection.

I don’t believe that your throttle plate is any different, someone correct me if I am mistaken but I don’t think any of the carbs in those series used different throttle plates. The extra holes in the arm were put there to accept attachments in various configurations and allow a greater number of variants from a single part. I would think simply removing that unused ball stud would be appropriate.

And in answer to the question of whether or not the part has a number stamped in it, yes it absolutely does. I am not where I can get to it now and check what that number is but I will tomorrow and post it. I am very confidant that this is an original part on my car but was modified to be used with a Holley that was installed a decade or so back.

Re: 1969 L46 throttle bracket

I think we are talking about two different things. (my fault)

I was referring to the needle valve that's in the carb base.. The dobbins picture dosen't have that and that's what I was wondering if I should remove. (I just hadn't gotten around to the extra ball stud yet)

That's why I was questioning if I had an incorrect base.

Not sure if that needle valve serves any purpose or not.

Re: 1969 L46 throttle bracket

Joe was dead on with my bracket; blasting turned up an N and no part number.

John

If you are talking about the idle mixture screw below the vacuum line; you have to have it to run at all, or at least run smooth. I've never tried running with them out; but screwed all the way "in" your engine will not idle and may be difficult just to keep running.

Here is a picture of the carb and brackets.

Re: 1969 L46 throttle bracket

I just didn't see it on the Dobbins carb, which made me question it, but I see you have it too. Very Good.

Back to the point of using photos in a referance book which are incorrect. It adds confusion.

Albeit good discussion.

One of two things about the BW photo:

1. It's mock engine and doesn't run
2. The stock idle mixture screws are shorter hence we don't see it and the ones we have are incorrect sticking out to the point of sight from angle of shot.

Re: 1969 L46 throttle bracket

I knew if I kept digging I'd find something else incorrect, like I don't already have enough to obsess about.
