440 help!
Hi all,
I'm looking for some help. I have a 1974 Raod Runner 440 that was rebuilt around 5 years ago. Do to a move in jobs the car sat for around 2 to 3 years. Now that I'm back I'm working back on the car to get it runnig. I can get it to start, but it dies quickly. The carb fills up with so much full that it dumps all over the manifold and ground. Thought it was just flooding and the carb needed to be cleaned. Any suggestions?

flood
sounds you're sharing flooding problems with North Dakota. Right, theirs are water issues.
flooding in the carb can come from: bad float, floats sometimes just give up, get fuel soaked and sink. then there's no fuel shut-off at needle and seat. bad needle and seat, doesn't seal. fuel pressure too high, bad fuel pressure regulator. because it sat for a while, I think the most likely is the float. That means putting in a new one and then adjusting the float level to spec. Might be able to do it on the car. This is pretty easy. If you buy a carb kit, it includes a needle and seat, so you can change that as long as you're in there. The float has to be bought separately. Doesn't come in the kit.

Before you do anything too drastic, ensure that your choke is tight. I have had a loose choke and the same problems occur. Lean up you choke and see if that doesn't solve the problem

I've never seen a choke cause fuel to just flood into the intake. A stuck/bad float, yes. A stuck needle valve, yes. As the car set for so long, odds are, the fuel shellacked the float or the needle down.
