Slick 60's

Was driving to lunch and the truck started surging, then died. I popped the hood and saw this:

I let it sit until it stopped leaking gas and then banged on the carb with a screwdriver handle. It cranked up after that and haven't had a problem in about 20 miles.

Stuck needle valve?

On the way back home it started idling rough and I thought it was going to die again. I pulled over and popped the hood while still running. No gas coming out of the carb like last time. I banged around on the carb some more to no real effect. Got back in and gave it a little gas and all of the sudden it started idling normal and had no other problem on the drive home.

I know the previous owner put in a new gas tank and rebuilt carb, but the fuel lines look old. I’m wondering if there may be rust sediment in the fuel line still.

Possibly some rust getting into needle & seat
Letting fuel in ....

Or could be a float "sticking" ....
Sometimes open , sometimes not far enough open ....

You could run some fuel conditioner like marvel mystery oil
In a tank & see if it helps , before you tear it down

Maybe an inline fuel filter near the carb might stop any rust from lines

I'd take the top of the carb off and see what might be in the float bowl. If you have sediment or rust, you still have an issue with the fuel system. Its pretty easy to replace the fuel lines. I'd also check the filler neck. If it is rusty inside, the sacale can get into your system. Also check the inside of the tank by pulling the sender unit. The other issue you can have is the issue with ethanol attacking all the rubber parts of your fuel system. The new gas is not compatible with old gaskets and float needles. Rebuild kits should be listed as ethanol safe. I had to replace the fuel pump and all carb gaskets on one of my cars due to ethanol.

I haven’t seen a fuel filter in the system. Did these engines have one originally?

mine has one on the fuel pump.some carbs have one in the fuel inlet to the carb, installing an inline filter is cheap and easy

Yep. Will definitely be doing that this weekend.

Thanks for the help guys.

Just to follow up on this thread, there was definitely rust in the fuel line. I spliced in an inline fuel filter a few inches from the carb and haven't had anymore issues from it. The gas tank is new but whoever put it in didn't replace the lines evidently. Also, they weren't real careful it seems and there are burlap fibers littering the bottom of the gas tank from the deteriorated seat backing. [sigh]
