Have you contacted Scott? That is the first step.

If the front throttle blades are stamped 314, it’s the big one. If they are stamped 315, it’s the small one.

Ahh, so never deviate from factory manual carburetor calibrations. Got it. I here ya. Thanks

There are idle mixture screws buried under the lead, just below the 2 aluminum plugs. Good chance that they are frozen. As Mattax said, that top screws controls idle air only.

If your neck isn’t stretched back over the backseat, then they are not opening

Kevin, looks like your picking up some rust from the fuel system. It only takes a spec to hold the needle off the seat. Your floats weight out fine. I’ll give it a good cleaning and bush this throttle shaft. Better do some flushing on the fuel system while I have your carb. There can’t be much...

You’re barking up the wrong tree with the gasket idea. The screw you mention is for idle FUEL mixture. Which is air and gas. What typically happens is the Idle feed restrictors are sized too small for today’s fuel. That is why it wants the screw backed out all the way. When this fails to run...

First off, I told you on May 6 I would have a look at it. Secondly if the fuel is soaking both gaskets then the needle and seat is not shutting. Heavy float or some debris in it. It has fuel dripping after shut down gauranteed. That is why it is coming out around the throttle shaft. Instead of...

With 180* or 190* T-stat, when you shut down and walk in the house, she will spike to around 210* -215*F. Anyone with a carter who thinks they have it bad, should see the tiny fuel capacity of a Quadrajet. Especially the early Quadrajet.

Today’s pump fuel is approximately 50% vapor @ 170*F.

Edelbrock told me “not for sale”

You found your problem

Both sides?

When the car is not running and fuel is squirted on the shaft it will find its way out. On a running motor the problem is almost non existent. I rebuilt that carb for him last year. I must have judged that shaft to be ok. The TQ has a lot of shaft hanging out there unsupported, so any wiggle is...

Get it warm and let it heat soak a while, check the timing at idle. Pull a plug, lay it somewhere that will be grounded and crank the engine. Note the spark color and intensity. Also I have read a couple posts that you mentioned have adjusted the carburetor. Check that your idle mixture screws...

5/16 factory small blocks and big blocks too.

Found it! That license plate in that article gave it away!

That’s what I’m looking for. Anyone here know that fella? I’d like to talk with him.

Has anyone seen this done or attempted. I wonder how much farther the scoops are apart than on an a-body. Just throwing this out there. Thanks

Ok, yes for the screw in and press in jets.

I have 2 850’s and 1, 1000 for sale.

I was with a customer. Returned your call and left a message.

Hang on pal, that 9077 likely was used in conjunction with the Electronic lean burn computer. It would have had a throttle closed switch on the passenger side and a lever bolted to the primary throttle shaft on the passenger side, and THAT is where the idle speed was set. Without the ELB...

Is there enough room to drill another hole up and over from the first?

Yes sir

Sounds good. I have had success with Permatex Cold weld and Marine-Tex.

I can sneak that in somewhere in a couple days.

Yep, that’s what they do. Yes, I bush about 50% of them.

There are a few subtle differences in baseplates. I have’nt had a need to try interchanging, but you could try it. I would rebush it for $40.
