Anybody know what this is?

I need to get a rebuild kit. (The one of two carb shops that still exist in NJ grabbed this from their core bin and rebuilt it for my HEI conversion on my van. Its leaking, covered in varnish, all steel parts are rusting and accelerator pump is not working reliably. I suspect the kit they used was not ethanol-freindly.) I'm told it was for a late non-lean burn passenger car with the jet up-sized.

Any info greatly appreciated.

4179021 chrysler no, R 8831 holley number orignal application early 1980 till feb 1, 1980 after that date running production change to 4179075 and R 9338 . This carb was for slant six federal and iternational emissions ,non ac and automatic tranny. There was a technical service bulletin about this.The part that changed was the choke vacuum diaphragm [ the pull off]. Driveability kit came with diaphragm chrsler no 4240064. and metal tag with new part number.If your carb does not have a tag . It was not updated?? There were no other changes to carb. The problem with early carbs was the choke was pulled open too far too early. Napa has the cups for accelrator pump with out buying the whole kit. buy at least two.

some thing like this but not sure, this one says for methanol http://www.napaonline.com/Catalog/Catal ... 0177403556

Thanks so much.
