I'm working on 1957 Gale 12S13 and my Lower Carb Bowl is cracked and leaking. Tried to JB weld it but it Still Leaks. I'm wondering if someone has a 303493 lower carb bowl for sale. I suspect the part number may have been superseded but that is the number I have from the Parts Diagram. Please P.M. me or email me at email@example.com if you have one you would be willing to sell.
