What caburetor is this?

rayjavu · 10-27-2008, 05:48 PM

I have a 1984 C20 with a 305 with a Rochester 2bbl. The engine isn't the original but it was in there when I bought the truck. Problem is I think the carb needs an overhaul. The carb has this on the side of the bowl " 7045112, then 525-YN" underneath that. I'm not finding either of those numbers listed as a Rochester carb. Can anyone help me decipher this?
Thanks

it may be a rochester made by carter, those numbers should still be good for getting a rebuild kit
