I have a 223 straight 6. It was running perfectly until I parked it for the winter. I just started it and now it won't idle for nothing. Acceleration is fine, just dies when it gets down to the idle circuit. I unscrewed the idle screw and sprayed some carb cleaner into it and it does go into the carb. What else could I try to do before I pull it and put a carb kit into it?
Thanks

 

With the truck in nuetral (or park) and the wheels chocked. Remove the air cleaner, rev the engine up 3000RPM or so and then either slam the choke plate shut or cram a rag over the carb throat. Let it up before it kills the engine and let the engine recover. Do this several times and see if that will clear it out.

Sometimes you get lucky
Good luck

I live in the desert so I am not an expert in this, But did you winterize your truck befroe you parked it. It could quite simply be bad gas. I have many vehicles I store and I use a fuel stabilizer in them before they go into storage. So you may want to consider draining your fuel tank and replacing it with fresh gas.

 

I'm not intimately familiar with the 1904 carb, but most have a tube that vents the bowl into the air horn (usually at an angle, about 1/4" diameter). That is a direct path into the bowl, so pour some carb cleaner into that before starting the engine. Let it sit 5 minutes or so, then start. While it's running if you can squirt more cleaner down that tube it will "mainline" cleaner into the whole carb, all circuits. Techron Fuel System Cleaner works well, but is not a spray.

RatRod is right, modern gas is really poor for storage, and besides that it tastes really bad
