I think it was off a 71 Charger 383HP auto or a C body. check numbers 6125S on copper tag and carb base. Pretty clean, I took it down, soaked it and scrubbed the carbon off most parts, but the inside is still black. Blew out all passages clean, reset mixture screws to 1.5 Missing that one little screw on the choke pull off, thats about it. Accelerator pump looked good. Ready to run. I put some rust prevention on the steel linkages that can be sprayed off after I took these pics. Those parts flash rust fast after a cleaning. $75 shipped.
