I just put a edelbrock 600 manual choke perf carb on, but I have some unanswered questions.
1-There's a hole on the back of the carb that's about 1/2" in diameter which I know is for the brake booster and there's a threaded plug provided in case it's not needed, but the hole isn't threaded. ???

2-The throttle cable and trans kick-down cable don't seem to have specific places to attach to the 600. Tips, tricks, or am I just not seeing the easy stuff. ???

3-If my carb is man choke and I don't have the man choke attached to a cable to control from inside the car, is there anything I need to do. I saw in the instructions where it states to wire the choke open or closed...I don't have the inst. w/me here at work, but any help would be great. ???

4-Does it matter which vacuum nipple I connect the vac adv for the dist to?
There are two vac lines. I believe the other one is for the a/c. It has a T-junction and I haven't traced it yet so I am assuming it's for the a/c. It's a very small gauge tubing thatresmbles the a/c vac line on another car of mine. ???

5-The large vac line in the front middle of the carb...What is that one for?

I am sure I am leaving out something, but I would appreciate help with these questions for now.

Aloha-- :cool: --Scott

Looking at the Front of the Carb >>> Small Vaccume Port on left is "PORTED",
Large Vaccume in Center is for "PCV" valve hook up.
Small Vaccume port on the right Is a "FULL TIME" Vaccume port.
Your Dist. Vaccume Advance line will go to the LEFT ONE "PORTED"
The small one on the right can be used for a Vaccume Gauge if you have one, or just plug it if you have no need for a constant vaccume source. ( or for you a/c controls that need constant vaccume)

#5. this is for the hose to the PCV valve.
#2. you may need some type of vehicle specific adaptor.
#3. Without a choke cable, yes it's a good idea to hold the choke open some way. Adding a cable and making the choke functional would be my suggestion.
#4. You will get many opinions here on using manifold or ported vacuum to your distributor. Manifold vacuum will be a port that draws vacuum constantly at idle. Ported vacuum will be the port that has vacuum only when the throttle is opened. There are many schools of thought here but I feel that there can be many factors to consider. Different engines and setups respond better to one than another. What were you using with your old carb?
I don't recall the deal with the booster fitting. Good luck with it.

For simplicity's sake there are no carbs I know of that have external porting for venturi vacuum. Basically that means two kinds of vacuum ports available...ported and non-ported (manifold vacuum).

There are some that feel that you can use either one but you cannot make an advance curve change accurately with light loads with non-ported vacuum (manifold), it's an all or nothing affair unless you balance the two against each other as some manufacturers did in the 70's with dual diaphram advance canisters.

Vacuum advance is connected to ported vacuum, recurve your distributor or limit total vacuum advance if you experience pinging with your optimum mechanical advance curve.

But there again ~~~~What Do I Know ?

Here is a link to Summit forthe items you need to hook up the throttle and kickdown cables. 8-)

Give this a look, Larry. You have been on here as long as I have so could be you have seen it. advance thread (http://elcaminocentral.com/ftopict-14071-vacuum.html+manifold+ported)
Alot of info there, food for thought. Like I said, many opinions on it. :)

Jim,
I do not recall ever seeing that post before, & I'm sure I'd remember it if I had. That IS a great thread, and thanks for pointing it out. It does have allot of information to it I find to be interesting and informative.

I realize that the rear hole on my carb is for the brake booster, but since the booster line is plumbed into the intake manifold behind the carb, I just want to plug it. The carb came with the pipe plug, but it turns out the hole wasn't threaded.
Tried n tried to find the right tap to run threads, but no-one has it. At least where I looked I came up empty.
Going to run a small freeze plug in the hole. I found the right size at my local checker.
I hope this works.. :-)

The back of my edelbrock 600 was threaded for the brake booster and it also came with a plug that I put in with no problems. Maybe you have a defective product?

Used a half inch expantion plug after boring the hole out a bit. Made sure no shaving were left in the carb. Plug went in easy with a small socket and hammer.
Now it's time to fab a return spring bracket since the a/c solenoid is in the way in front of the linkage and the throttle cable and trans kick-down & bracket are in the way to the rear.
No too good @ fabricating, but it's not for show so I'll bend and drill something that'll hopefully serve the purpose.
Thanks for the support...

Everything is hooked up and I started my '84 yesterday.
Idle seems low, but I don't have a tach yet. In gear it still idles ok, with a/c on idles ok. Idle solenoid needs a little adjustment, but I'll adv the timing a bit to get the idle up a bit. Haven't driven 'er yet.
Maybe today. Not sure about taking 'er out in traffic and dying. We'll see. No confidence in my handi-work.
Thanks for the help,
Scott

that advance thread ignition 101 is great. It has me thinking at a whole other level...
