Trying to ID a Carb

[dunoon2]

I have a 57 520 that I need to id the carb, it's a duplex and I can't hardly read the ID tag, it looks like d-lx 107, I know it's a weird carb. I was told many years ago is that it is a replacement carb. Used on all 2 cly of that time. It isn't a small bore body. It's like the body used on 620 and 720's but jetted with 520 jets. I'm going to rebuild it and need to know the ID#. Thanks

Service Manual SM-2024 lists DLTX-99 (gasoline) as the largest number for Marvel Schebler duplex units and it is used on 520 & 530 tractors. Same manual list DLTX-97 (all fuel) for 620 & 630.

Maybe that will be of some help? I assume yours is for gasoline so those all fuel numbers probably aren't of much use.

There are kits available for a DLTX-107u but it says that's a single induction type.
