The Stovebolt Site Forums The Shop Area Engine Shop Carter Carburetor ID question

Going to rebuild the carburetor now that I've got the gas tank sraightened out (no more rust!) and I'm trying to figure out what carb I have.

Based upon Carbking's website , I should have a number stamped into the bottom of a Carter W-1 (which I'm pretty sure I have).

That number appears to be 503. It's a little hard to see it, though.

I can't find that number on any list.

It's a carter, and it's cast iron. Anyone got any ideas?

Thanks in advance!

Okay, I've had another look.

It's definitely a W-1. I found it cast into the outside of the unit.

The number on the bottom, after closer inspection with a trouble light and a magnifying glass is actually 603.

I'm still not sure what the heck this thing really goes to...

This may be a question for carbking.

I have the same carb. Carbking helped me identify it as a Carter W-1 manufactured for 1949. It is a unique entity within the Carter W-1 line. Try the search function for more info. Hope this helps.

I was afraid of that...

Thanks for the info.

At least my accelerator pump is still good. All I really need is a "cleanup" kit with gaskets and ball valves. A little carb cleaner and it should be right as rain.

I'll start looking for a 574, though...

Yeah, when I changed over to the Rochester, I rebuilt my W-1 before I retired it to a box over 25 years ago. It came out of the box a couple of weeks ago and I dutifully took it apart for inspection and re-cleaning before installation. I was surprised to see that the pump leather was still perfect. SO far so good - runs like a champ. My thanks to carbking for his guidance.
