I was rebuilding the carburetor (Holley 2245) and I broke a part. That part is punched in rather than screwed in. Is there a replacement part, and tool to remove the broken part, as well as one to punch in the replacement?

Here's a picture... Is that broken one a main jet? If not, what is it? Can I replace it?

 

Oh Boy... My suggestion would be the wrecking yard for a parts carb, if you dont find a source for the parts and tool.
But you might check with Doctor Carb... >>>>> http://www.carbkitsource.com/
