Doesen't Run
Check and see if you have air bubbles in the Fuel Pump Sediment Bowl, this will give a sign of air getting into the fuel. Also after sitting that length of time you might want to take the carb apart an give it a good cleaning.
When was the last time this was done? You may discover that it needs a overhaul.
Word of caution on the Ether it could cause you to pop a piston, and with the backfiring if you do pour gas into the top of the carb, could cause a fire in the process. Make sure you have the air breather on, this is not just for filtering air. It also serves as a flame arrestor. Last check the points, after sitting for awhile they will develope a film , and need a cleaning. If the truck was running good when you parked it, chances are its a very minor thing, so don't go adjusting a lot of thing that don't need to be, good luck, and Merry Christmas.

I've changed out the carb with a rebuilt carb.
I haven't worked on the truck yet. I've been taking in all of the suggestions. I'm off next week and plan to use the suggestions.
My goal is to have the truck running next week. Hopefully, I can do it.

On more than one occasion, I have had old vehicles that sat for a long time, and should run (good spark, gas, etc) but would only remain running for as long as I poured fuel down the carb or sprayed ether into it. After a tip from an old tractor collector, I learned that a teaspoon of motor oil in each cylinder would restore the seal at the piston rings and the motor would then create enough vacuum to pull in a fuel/air mixture. Once started, the oil burns off in a few minutes. Helps reduce piston scuffing on a dry motor, too.
A couple of times I've made this suggestion to younger guys who looked at me like I was senile, and both times they reported that, to their surprise it worked. If nothing else, it's got to be the easiest, cheapest thing you can try.

This is the second time I've heard of this method. So, do I undo the spark plugs and pour a teaspoon of motor oil in it? Do I then immediately put the spark plugs back in and try to start her up or wait a little bit?
Thanks, Ilya
Thanks, Ilya

Oil in the hole
Actually, I don't usually pour a teaspoon full of oil down the hole, especially on V-8s. I get a pump type oil can and get the nozzle down into the spark plug hole, aim in the general direction of the cylinder wall and give two or three good squirts. On a V-8 I aim for the high side of the cylinder, so that it can run down the sides. I don't recall that I ever really waited either. Ususally by the time I put the plugs back in and the wires on I figured it had migrated around enough to try, and so far, that's worked just fine.
There's not a lot of precision to this process.

She Runs!!!!
The '51 started mysteriously yesterday. My father-in-law moved it back a few feet from it's parked position to clean it up before moving it to storage. He cranked it one time and nothing. Cranked it a second time and "bam" she fired right up. We ran it for a few minutes, then stopped it. Restarted it again with no problem. All we needed to add was brake fluid.
She runs like she did before. I wonder what the problem was?????
I'm just glad she's running. At least I can enjoy one of the two trucks.

Sorry. No clue what the difference was. Just glad she is running again.

I was reading through an old Ford repair book I picked up at the local used book store. And it said that a low charge on the battery even though the engine will turn over can cause that problem. It says if you can push start the vehicle then the battery is most likely the problem. May, or may not, apply to you but I just thought I would pass the information on.
