As others have mentioned, this is probably a fuel related problem. If the truck has sat without running for some time, the fuel has probably gone bad.

Where to start?

Can you disconnect the fuel line from the tank to the fuel pump, and then connect the fuel pump to an external tank (possibly a portable marine outboard tank) with new fuel, and also change the fuel filter? This would test whether the fuel pump is OK.

My GUESS would be draining and flushing the fuel tank, and replacing the fuel filter would go a long ways to solving your problem.

As to the argument on Rochester vs Carter, lots of pixels on the internet have been disturbed on this subject; but we SELL Carters and GIVE AWAY Rochester 1-barrels. That should explain our stand on the issue:

In your case, I doubt either the carb or the ignition are at fault.
