Holley Carburetor swap
 
Sometimes it is better to be luck than good , you sure got luck on that one. Might have burned ever thing in the shed, the way you have it packed in ther
 
In its hay-day our local town had a Holley carburetor plant that employed well over 600 folks and made many of that carburetor you are working on. Around 1963 or so best I remember over 3 thousand a day.
 
Very nice truck. I have a 58 3/4 ton 4by 4 and this it a truck compare to then new stuff out there. Also have a 3/4 ton 53 pick up that has the vacoomed governor under the carb that only let it go about 45 mph down the road. I love the old trucks like these.

I've accumulated a few of those IH trucks over the years. I got this yellow R series in the video at a farm auction in 02. It was a no-start at the auction so I got it fairly cheap. It had been updated to a newer BD264 engine which is a good improvement on the original smaller engine. Runs great when this Holley carburetor is working right.

ook's like your truck has a vacuum leak. I don't know anything about the International trucks but I would guess if it had vacuum wipers and/or a brake booster they would likely be powered buy a vacuum pump and not a hose. It sounds like a rubber vacuum cap is cracked or has fallen off. Could be a cracked carburetor spacer.
 
Is the exhaust manifold cast or mated to the intake in such a way there could be exhaust transferring to the intake via a burned through exhaust manifold?

They are two separate manifolds that bolt together down below the carburetor. And now you mention it, there is a break in the exhaust manifold where it bolts to the intake. But this different carburetor did make quite an improvement so I don't know if the cracked exhaust is having any effect on the running.
 
I guess if you had been using a remote starter, you would have seen that spurting gas right away. I think someone is looking out for you. LOL
 
Last summer, several of us met at a restaurant with our cars. I have a 1966 SS396 convertible and one of the guys wanted to look at the engine number to see if it was original to the car. That's the only reason I would have opened the hood and the minute I did I saw black covering the side of the engine. There's a short fuel hose from the metal fuel line to the carburetor and it had wet gas on it as the hose had deteriorated and sprung a fuel leak. There's a vacuum hose from the carburetor to the distributor and it was gone. It had been on fire which is where the black "soot" came from. Must have just happened about the time I shut the engine off. I would not have made it home and if I had driven any further there would have been one less SS396. Check your fuel hoses!
 
(quoted from post at 08:33:39 11/27/20) I am not following why you are swapping carburetors.

David, you must have missed the part in the video where I stated that the truck had been running like crap and nothing else I did seemed to help. So I figured taking a carburetor off a similar truck that had been running good would be a good test.
