Default Help starting engine that's been sitting for years... Ford Sraight six

My neighbor has a 82 Bronco with a straight 6 engine in it. He's been trying to get it started for a few days and I poked in and tried to help yesterday for a few minutes. I could get it to fire and stay running while injecting starting fluid in the carb, but as soon as we stopped spraying the engine dies.

They've had the same gas in it for 2 years I suggested draining the gas in the thank then putting in some new high octane with a can of octane boost in it and see if it would fire. Well, they didn't drain out the old gas first they just added 5 gallons of fresh and a can of octane booster. The gas tank had about a quarter tank before adding anything.

It still won't fire. I know the following for sure...

Fresh battery
Fuel to the carb
Fuel is being pumped into the carb
Good spark
Runs on starting fluid

I am assuming it has to be fuel related but I am not sure if what they did was able to bump up the bad gas to something usable?

I'm just trying to help the family out, any suggestions?

Drew, did you check/see if the accelerator pump is delivering a squirt?

While it may look different, the carburetor should behave the same as the ones on our 40, i.e. there should be a squirt of gas down the primary when you hit the pedal.

The carb jets are likely clogged with old gas residue.

Be sure the choke is fully closing, and I'd vote for clogged main jets or a stuck float.

X2 for stuck float.

Also, those old ford ignition modules we notorious for acting wierd.....ie if the engine will only fire with the key in the start position, but not in run, I would have the ignition module tested

if you can get it to run... rev it till its gonna kill itself then slap yer hand on the carb to where it feels like its gonna do an airplane suck your ass into the lavatory move. The suction can sometimes pull trash through the jets and let fuel start to move normally through it again.

Best explanation of vacuum charging I've ever heard. This is exactly what I did when my 40 was first firing up after 15 years of hanging out in a horse corral.
