I'm going with the fuel delivery problem... clogged line, bad fuel pump, out of gas, or water in the gas.

122 wagons ain't prone to water getting in the gas, so I'd rule that one out for now. Get a piece of... perhaps 5/16" or so copper pipe, and plug it into the piece of fuel line that goes into the fuel pump, and and blow in it... have an assistant listen for bubbles in the tank.

If you can blow through it but no bubbles, the line is clear, but you're out of gas. If you can blow through it, and hear bubbles, you're OK.

Make sure you can blow through the line between the carbs and the pump... with said line disconnected from the pump.

Replace or install any and all in-line filters.

After you've determined that all the lines are clear, replace the fuel pump and you'll be happily motoring along your way. My money is on the fuel pump being the problem.

I always keep a spare pump with me... only takes about 5 minutes to replace roadside... has saved me more times than I can count.

Soounds like a wonderful car... 71k original... geez, I'm envious!
