I have a Rochester quadrajet 4 barrel (thanks to a few guys on the site). I need to know what model number this is so I can buy a carburetor rebuild kit from mikes carburetor parts.com. The 2 sets of numbers i was able to find was 20240MD 1619 and 7037895. I have attached photos of the numbers and their locations. Any information would be greatly appreciated. Thanks.
What you're calling 20240MD looks to me like 29240MD in the photos. Do you have a clear photo of the 7037895 number? I haven't been able to decode that number from any of the online decoders I found.
If I’m correct, you bought this carb on this site as a 29240. That is a 1969 carb for Buick. 29240 is the number you will reference when looking for a rebuild kit. Most kits will service a good number of carbs so call the vendors if you don’t see 29240 listed on their website.

I believe that the 29240 1619 is the number that matters. I'm not sure that the second number is actually a nine, but that's the way I read it.
