A little over a year ago I purchased 2 Holley 600 carbs from a member here. Carb numbers are 1850-11. Under the carb numbers are 1129. what does that number mean? Is it a manufacturing date?
Now these are vacuum secondarys and my plan is to use them on my edelbrock TL5 2x4 manifold.
Someone in the past cut the shaft and linkage on the choke and the upper plates flop around. So I tried flattening the choke plate to remove it but had no luck. What are my options here as I dont plan on using a choke. I am including pics of the cut shafts.
Next I have taken the the first carb apart and cleaned it overnight, washed the parts off and blown everything dry. The carb has 65 jets in the front and the rear is a metering plate. The bowls have what they are calling non adjustable needle and seats once its assembled.
I ordered quick change vacuum secondary housings with spring assortments and I plan on tying the 2 secondarys together.
This will be my first time ever using a 2x4 setup so is there anything I should do different as I put these 2 carbs together? Secrets?
Lastly I need to buy a new accelerator cable and will need ideas on how to mount the carb end. I plan on mounting the carbs sideways so my linkage will need to be mounted around the center left side of the intake. What have you used? Any pics of yours?
Thanks guys.

I presume that a TL5 is a tunnel ram?
I believe that Edelbrock and speedway both make side mount 2x4 linkages - no reason to reinvent them...

What motor is this going on and what will be the intended use?
 
Sorry for the delay getting back to this thread. I will do some drag racing and some street driving. Yes it is a tunnel ram and I already have the linkage for it. What I was referring to was the throttle cable brackets to hold the cable. As for motor it will be going on my 408 10.5-1 .600 lift solid roller cam.
thanks Rod
 
I’ve gotten no reply’s back on the choke shaft or plate. I’m thinking cutting it because it’s not useable now so it don’t think I can hurt it anymore then it already is?

I never run a choke on anything. Waste of time and they don’t work very well anyway. Mill them off and be done with it.

Are you mounting the carb’s in line or sideways? I prefer sideways. If they are in line you have to take them off to make most any tuning change.

Also, you’ll really need to find a way to figure out if the secondaries even open.
 
I am mounting them sideways. I will try the Bobbie pin test to see if they open and how far.
 
When say mill them off you mean the hole encapsulated frt section down to the center body?

Yep. Right down flush to the raised area that centers the air cleaner. Take all that crapola off of there.

Before I had this little mill I now have, I used to cut them off with a hack saw and then file it down flush. It’s easy if you are careful and have a nice, aggressive bastard file to get the materiel down and then end with a nice, sharp fine file.

Or mill it if you have access to one.
