Can't keep motor running
I recently bought a 79 f350, 351m c6 trans. When I bought it we knew it didnt run the guy swore up and down it was just a bad carb, after seeing how bad it looked it made sense. Since then I have rebuilt the carb, replaced spark plugs, wires, cap and rotor, fuel pump, new rear fuel tank with all new fuel lines. New ICM, new voltage regulator, battery, and alternator. The truck start right away but does after about 6 seconds, every now and then it'll start and stay running for a while to the point where I feel like it'll make it around the block. It makes it about 4 houses down then dies again. We've tried adjusting the carb and still no progress. Hoping someone has a recommendation for what to look for next, at this point anything will help!

We replaced the distributor last night and got it all timed and drove it around the block a few times and then into the garage. This morning after I changed the oil went to go to the gas station to fill it up and made it only a couple houses down before it started cutting out. It will halfway idle on it's own, but the second I'd give it gas Itd sputter and die. I'm starting to think this thing is cursed, going to look into a new carburetor, any recommendations? Right now it's just the stock motorcraft 2 barrel 2150.

In general when ive had spark issues in trucks their was lots of misfiring but the motor still ran. When it was fuel related the motor doesnt run at all or cuts out due to shortage. Just my experiences. I could absolutely see this being carb related.

I went through 2 cans of starter fluid and sprayed every inch of that motor and the idle never changed

The guy I bought the truck from removed both tanks and just used some random tank behind the seat. So I got a new tank all new lines and pump and already put a new filter in.

Agreed. If you've eliminated vacuum leaks, PCV, fuel delivery, and ignition problems, I'd try another carburetor. But of course that's the first thing I do anyway since there are much better carburetors and intake manifolds available than Motorcraft
