10 minutes of success, followed by the roughest ride home.

Happy holidays everyone!

I'm new to the forum, but excited to get some assistance from people who truly appreciate what we have. My rebuild is Elvis. He's a '65 fleetside long bed with the straight 6 292. I have had him for 3 years, but sadly only just got the chance to really start getting work put in. I purchased him from a mechanic at the auto shop at my last base who told me the truck was running, just needed a new battery and some work on the lights. Definitely not the case, but I've almost got it going. My main issue right now (lighting aside) is that I can make it flawlessly about 5-7 miles down the road. But, when I turn around to go home he starts choking down like he's out of gas. New carb. New fuel filter. No leaks anywhere. And once he cools back down, runs fine until another few miles then repeat. I'm an aircraft mechanic, but new to vehicles aside from the basics. Who has some advice?

Check your gas tank vent

I love and hate how obvious and easy that is. Will do first thing in the morning. Thank you!

The pickup sock in fuel tank is probably getting plugged, pull it out and clean it.

Coils act like that when they go bad and often will feel quite warm to the touch after operation. If it's not fuel, well then it's gotta be spark right? A clear fuel filter will help you keep an eye on the gas supply.

I had the same problem on a 1966 Chevy truck I bought in Oklahoma City and tried to drive back to Arizona except it was plugged up at the elbow after the fuel tank screen inside the fuel tank. I had to remove the pick up tube from the fuel tank, remove the screen from the pick up tube and run a stiff wire in the tube to get it cleaned out.

faulty condensers also produce the same symptoms

[spacedebris]

could it possibly be the choke sticking?

[buds56]

Put in a new condenser they're cheap and easy to put in.

Any up date?

Can almost guarantee when this happens the hoses in the fuel line are collapsing from the new gas and age, these hoses are often overlooked. The one from the frame to the fuel line on the tank is usually the culprit but replace them all it's worth the time and couple bucks. Also replace the hose clamps. Blowing the lines out can't hurt either as long as they are apart.
