Guest 1963starfire Posted April 3, 2005 Share Posted April 3, 2005 Can anyone tell me what each number represents on the tin tag on the carburetor? #7023051 1963 Oldsmobile Starfire with A/C.Thanks Link to comment Share on other sites More sharing options...
ronvb Posted April 3, 2005 Share Posted April 3, 2005 Here goes: 702 is a prefix code for 1960's Rochester carbs, 3 is the year produced-1963,0-model carb,5-division-Olds,1-transmission-even numbers-automatic,odd-manual trans. The 5th digit is not always accurate as 0 should be a 1bbl carb and that carb #in Motors manual is a 4bbl and the 7th digit same thing as there were not too many manual trans for OLDS.Hope that helps.ronvb Link to comment Share on other sites More sharing options...
Guest 1963starfire Posted April 4, 2005 Share Posted April 4, 2005 Thanks very much. You are correct.My Starfire carburetor is 4GC 4bbl and it has an Automatic transmission.Not many manual transmissions in the Oldsmobile line.Thanks again Link to comment Share on other sites More sharing options...
carbking Posted April 4, 2005 Share Posted April 4, 2005 A little additional information. While it was often true that the 7th digit being odd denoted a manual transmission (primarily Chevrolet and Pontiac); it often meant automatic with air for the other divisions. In this case the non A/C carburetor was a 7023050; the one with A/C 7023051.You will find MANY anomalies to the guidelines, which are just that - guidelines. ALWAYS best to check a list by tag number for exact application.Jon. Link to comment Share on other sites More sharing options...
Guest 1963starfire Posted April 4, 2005 Share Posted April 4, 2005 Jon, thanks for that info. The reason I have asked the question. I have found arebuilt carburetor that was used on eithera 1963 Jetstar or F-85. The tag numberis so close to my Starfire I was wonderingif it would work. This carburetor number is 7023054 my carburetor number is 7023051. I believe the the Jetstar used a two speed transmission. The Starfire has a four speed unit. Not sure is this carburetor has air conditioning or not. Link to comment Share on other sites More sharing options...
carbking Posted April 4, 2005 Share Posted April 4, 2005 The 7023054 is for a much smaller engine and SHOULD NOT be interchanged for the 7023051.This listing from our website may be of interest: Oldsmobile carbs 1940 - 1965 Jon. Link to comment Share on other sites More sharing options...
Guest 1963starfire Posted April 4, 2005 Share Posted April 4, 2005 Thank you, that is very interesting.Nice website too. I see you sell carburetors too. Do you all charge a core charge? I tried to rebuild my carburetor myself, but I never could get the floats adjusted exactlyright. I've lost track of the times I've taken the carburetor off to adjust them. The floats must be set exactly right othterwise carburetor will flood itself to death. Link to comment Share on other sites More sharing options...
