Default Loud squalling noise from Inline 6

I am having trouble with my 250ci inline 6 stock engine. It won't idle. Carb looked dirty, black gunky inside so I have decided to rebuild the carb. The truck is also now making an awful sound like a cat squalling. Anyone that could help me figure out the likely cause, I would appreciate the help. The truck still has the generator setup.

Can't help you until you tell is where the noise is coming from and when it does it. Is it the motor or the chassis or steering or what? While idling, while driving?.... You say the truck is making noise, that's a big area. Could be fan belt? We can't hear it from our house. Gotta help us a little.

Black gunk in the carb probably means the same stuff is in the fuel filter too. And the tank. As for the squeal, it's probably the tail lamp that needs greasing. It happens alot.

I'm guessing radio between stations. I have seen FMAP's cause many times also.

Glad I could give you guys a good laugh. Pretty sure its not the radio since the truck does not have one. I will change the fuel filter when I rebuild the carb. I haven't been able to keep the engine running to get close to the noise as I have no help and the truck won't idle. I think it might be a bearing in the generator maybe.

I wouldn't be surprised if it's the water pump. They can make some noise. lol

When a water pump goes out do they usually leak? I haven't seen any indication of leaks so far.

The fan belt looks ok, no cracks or bad spots and it is tight.

Buddy of mine had one go out and never mentioned it leaking. My 46 case tractor's pump leaks but doesn't squall. lol The seal is shot.
