The Stovebolt Site Forums The Shop Area Engine Shop Carter W1 483s/574s issue

Hi all, well I'm back this time with a Carter W1 question.

I picked up a 483s or 574s recently (421 stamped on the bottom and body) and noticed the tube at the top of the carb that sits at an angle at the air inlet is split about half way down in half. I think it might be called the air horn pipe but definitely don't quote me on that.

The carb appears to be in good shape except for that. Does that tube need to be repaired for the carb to operate properly? I looked around online and was unable to find a replacement tube. Is it repairable and can it be done at home or does it require specialty tools that a only a carb shop might have. It looks like it's pressed into the casting but I'm not sure.

Here's a picture for reference...it's the little tube at the top of the carb opening that is cracked on mine....

I went and looked at my spare I have, the tube is a vent for the float bowl. You might be able to pull it out and replace it with a brass tube from the hobby shop or hardware store. Looks like the top is cut at 45 degrees. I suspect it's pressed in. You also might be able to work it back into shape and slide a bigger tube over it.

Hi Joe, thank you for doing that.

I think i'll try and fiddle with it, if I can get it out with out doing more harm then good that would be nice. Otherwise, I may just try and slide a section of bigger tube over it and silver solder it on. Strange place to have a metal failure, I have never seen one of those vent tubes cracked like that on a carb.
