carbking Posted October 12, 2020 Share Posted October 12, 2020 (edited) In a different lifetime, I started to write a book on Detroit Lubricator and Stewart carburetors. The Stewart Carburetor Company was a division of the Detroit Lubricator Company, so I have included both. I have long since realized that the book is not going to happen. But I thought some might like to see the customer list, at least of what I have been able to research. And apologies beforehand to any of you who have Graham blood running in your veins. I have spent hundreds of hours poring over Graham material, and have come to the conclusion that it is much easier to work with Toyota books than Graham (and no, I do not read and write Kanji!!!). One other apology, while I can line up table columns on my own website, doing so on this forum is an art that has eluded me! As always, with any of my posts, documented corrections are ALWAYS welcome. No ego here, simply a desire to organize and share information. Jon.

West Peterson Posted October 12, 2020 Share Posted October 12, 2020 Curious about the two different 1930 Packard 734 O.E. numbers. Was that a difference between brass and pot-metal bowls? Or....???? Link to comment Share on other sites More sharing options...
carbking Posted October 12, 2020 Author Share Posted October 12, 2020 West - yes, there were some other differences as well. The Packard section is easier to understand if one checks the listing on my website which gives more information than the index: Packard Detroit Lubricator made running changes. On the Packards, the identification is in the format: myynnn m = month (A=January, B=February, etc. yy = last two digits in the year (29 = 1929, 30 = 1930, etc.) nnn = is what we would normally think of a tag number Example: A30753 was produced in January 1930, and was tag number 753. Checking the chart shows this to be used on a 1930 726 or 733 from January through April. Those carbs built in Feb, Mar, or April would have different letter prefixes. The 734 used two carbs: A-30825 (Packard number 178032) from January through February C-30825 (Packard number 179852) from March forward Difficult for me to tell from the Packard literature, but seems there was a high compression cylinder head, and a low compression cylinder head. The calibrations in the carburetors were changed accordingly. Jon. Link to comment Share on other sites More sharing options...
carbking Posted October 12, 2020 Author Share Posted October 12, 2020 West - checking the parts list: Low compression head: Aspirator valve 180192 Metering pin assembly 180193 High compression head: Aspirator valve 179908 Metering pin assembly 179850 There are other differences as well.

West Peterson Posted October 13, 2020 Share Posted October 13, 2020 Thank you for the information. The 734 DL dual-throat carb on my shelf has number I-30825. I'm assuming that indicates a September build. The car was delivered in July, so this is a replacement carb?. Correct? Link to comment Share on other sites More sharing options...
carbking Posted October 13, 2020 Author Share Posted October 13, 2020 Correct - DL did use the "I" in the date coding. Some manufacturers do, some do not. Jon Link to comment Share on other sites More sharing options...
