I went to check out the condition of the shoke stove this morning, and behold...

I don't have one.

I DO, however, have an elevtric choke. Good, right?

Maybe?

because this doesn't look OE.

I'm thinking this needs maybe, kinda to be blocked.

Do I need to attend to this immediately, do I need to buy a specific block off plate for 25.00, and yes, I need to get the various varmint leavings
out of there soon.

I'm assuming these bolts are gonna be a bear to remove.

just a hunch.

The bolts will probably not be that yard to remove, mine weren't. Might require a vice grip due to rust changing the size of the bolt head, but try a
metric wrench first. 14 and 12mm are both a little smaller than 9/16 and 1/2, respectively. Run the engine a few minutes to warm the area, and then
hit it with WD-40 or ATF and let it cool and draw it into the crevices while you find the right size wrench. Vacuum the mouse leftovers out before you
spray any penetrant or they will be a mess.

The pipe that makes the stove rusted out on mine and was blowing exhaust out, so I fabbed a plate and gasket and sealed it off since I also have an
electric choke.

Well, it looks pretty knarly there, so I'd be thinking about a block off plate. Removing the bolts may be a challenge. Those two openings are
connected through a tube, so they might not be leaking, but you could thread them and insert a screw in each with thread sealant.

with the condition of the wiring loom in the area that was completely melted, I'm sure it's leaking. perhaps this will be my first project
"fashioning" a piece for my engine. Even something as simple as a block off plate would be pretty cool.

It's not an OEM Quadrajet. Looks like it maybe a Holley.

Not a Holley guru, but I think that vacuum port is to activate that diaphragm that inhibits or allows the secondary venturi of the carb to open. Put a
hand vacuum pump on there and watch what happens.

You best bet for a permanent repair is to remove the stove pipe and replace it with a block off plate and new gasket.

Jim K. (Applied GMC) and others have both the plate and gasket. Replace the bolts also. I used stainless bolts with anti-sieze in case I ever need
to remove the plate again.

If the bolts will not remove easily, use Kroil and soak them daily for 4 or 5 days. They will come out. Heating the manifold between soakings by
running the engine will help but you probably can get them loose without it.

Mine came loose without having to soak them more than once.

Im pretty sure the holly vac secondary wprks off internal vacuum.I also think that fitting is for a vac pull off for the choke, but not all have them.
Look for another fitting at the air horn near it.

IMO you would be better off with a properly tuned Q-jet on our application.

The Port you are pointing to on your Holley Carb photo may need no changes (I do not know what that port is for because I don't know what model it
is) Put your finger on it and if there is a vacuum pressent then something needs to be attached or it should be plugged. Your electric Choke Holley
needs no changing as far as the choke goes.

Here are two Holley illustrations showing features and vacuum ports.

One shows the port you show as open (leave as it is) the other shows a hose going to the air horn both as fresh air for the choke. Does this help?

thanks John! Those are great pics. I'll get the part number for my carb and investigate further.

The holley carb is not so good, ok it is working but a original rochester would be better..
And if your choke tube that goes in to the intake is not leaking now just leave it as it is, is can be a pain to seal it again, even with a new block
off plate
