Right now the airflow is probably sucking the throttle fully open.
That would explain the high rev after it starts.

Your throttle set up looks like there was a Super Six there once. You might need to get a cable set up to make the little Holley work. I have some good pictures of how the Holley should be set up. Click on the red link below my name and put them in slide show mode for better viewing. You might be doing some junkyard scrounging to get the needed parts. Right now the throttle rod is 90 degrees off from making the carb work. A cable set up would solve that problem.

Post subject:  carb linkage

I noticed in your video that the carburetor throttle linkage is being sucked open as soon as you start it. That's why it's dying right after it fires. If you want to get it to run while you're waiting on the correct linkage, just put the spring haning from the intake on the carb linkage to keep it closed. It should give your a chance to fire it over without blowing it up. You're lucky it hasn't stayed running. I'd hate to see a rod hanging out the side of the block.

Good luck.

Could you school me on the correct carb for the super six? Is the current super 225 that's in there not a super six?

I'm going to check out your pics now. Finding close up pics is one thing i've struggled with lately.

Gonna do that now. Thanks for your advice.

Quick question, which way does the throttle open on a correct setup? WOT towards drivers side?

The "Super 225" sticker simply means the engine is 225 cubic inches. That was a marketing ploy used in the 60s on Dodge vehicles.

The "Super Six" was a late 70s and early 80s option on the slant six that included a two barrel carburetor, a special air cleaer with the Super Six decal on it, a special kickdown, and a 2 1/4 inch exhaust line. See HERE. The factory correct carburetor for a "Super Six" is a Carter BBD (with special features to make it work right on a slant six) or a Holley 2280.

To determine which way the throttle should move at wide open throttle, open the choke, look down the throat of the carb, and work the throttle.

Just looked through you pictures and one thing caught my eye. You have a close up picture of your vent bowl and there's a valve that's holding the top hat.

The carb that's on there now doesn't have a valve at all. I did a quick search and was directed to another mopar forum where the same question was asked and he was told there should be some type of spring loaded valve there holding up the vent bowl armature.

Thoughts?

For now i also used that spring to hold the throttle valve closed. Sprayed a little starting fluid and it started but died out within a few seconds (2-3 sec), However it wasnt screaming, it sounded like a normal idle speed. It seems to me that she wants to run but starves out. I've checked fuel flow to the carb multiple times by removing the line that feeds the carb and there's a steady flow. What i can't confirm is what's happening INSIDE the carb. I'm assuming everything is "okay". If i work the throttle valve it squirts fuel down the carb.

okay now i'm starting to connect the dots. I stumbled across that page a few times in my search for pictures. Now i see what you mean about the super six package.

I believe what caused Ted to say your engine used to have a Super Six was the bracket bolted to the side of the intake that sticks out towards the radiator. I respectfully disagree with ted's analysis. That bracket does not look like a Super Six bracket to me. I suspect that bracket was the rear brace for the A/C compressor that is now missing from the engine. Looking back at some of the other pictures you have posted, there is a large bracket with four holes on top of a large flat plate mounted above and to the driver's side of the water pump. I believe that is where the A/C compressor (or possible some other accessory put on the 60s era D100 trucks) would have mounted. I believe the bracket from the intake would connect to the back of the compressor.

I do not see any signs that your motor was ever equipped with a Super Six system. It looks like you have the throttle return spring figured out. Here is a hint- if the spring pull the throttle closed that way, which direction does the throttle open to get to wide open throttle?

I had goof ball moment by asking that question. It took me a split second to realize which way WOT is. lol Not seeing things clearly.

Here's a picture i found on the web i used for comparison. LEFT is my picture, The RIGHT is one i found online

The only difference is that the picture on the right doesnt have a kickdown cable. The truck i have has a rod kickdown cable that at the moment is just loose.

Good picture, I have not seen that linkage arrangement before. Either way your missing a few linkage parts and may need to visit the local junkyards..... My old 68 truck used a rod that rotated.

My carb is just a newer version of the Holley 1920. It also has the vent line on the left that goes to a charcoal canister. Part of the emissions that captures gas vapors. I believe they started that in the 70's. My car uses the charcoal emission canister. You can see it over by the alternator to the left of the over flow tank.

Yes, I was looking at that plus the nuts and triangle washers on the intake manifold. They were put on backwards, some replaced with washers and lots of RTV smeared. I thought some one took off a 2 barrel "Super Six" set up and installed the single barrel manifold and never hooked up the throttle linkage. Learn something everyday.......good photo of the red SL6 linkage.

GREAT NEWS ..Got her started and idling by hand. Finally figured how to hold the choke and throttle in the right spot for her to start.

I can't thank you guys enough for your prompt responses these last few days.

Now just have to locate the linkage. Going to spend some time tomorrow hunting down a complete cable throttle linkage

This is basically what i need since this truck has the rod kickdown.
