Just bought a 1929 Chevy 4 door and need to rebuild the carb, I think it might be original but from what I read I can't figure out if it is. It does have a few markings on it. Close I can tell it is has the short plunger (Leather bad on it) on it making it a 125s I think. I have posted some pictures to look at and tell me what you all think?
Markings on it are as follows: patents 1,536,043 (On outside of bowl) & 227-98 and the logo appears to be RJ above that (Inside bowl) (Picture attached)

Dave, Welcome to Chat and to vintage Chevy ownership. There are a couple of guys here who will be able to answer all your questions about your carb. They will probably find your post before the day is over. I clicked your YouTube link. I didn't stay long but it didn't look like 1929 Carb related.
David, Welcome to 29 Chevrolet ownership, and VCCA Chatter forum. I regret to tell you the carburetor is not original. It is a 1950s era replacement. The original is a Carter RJH-08. There are two versions the 125s with an external short accelerator pump and the later 136s with the smaller diameter but longer pump.
I can' t tell from the photos but Marvel, Johnson, Tillotson made similar looking carburetors. I am not aware of any kits for those carburetors. You might get by with making the gaskets and plunger leather
I have rebuilt original carburetors in stock, not sure about the 125s but do have 136s and 150s. Most use the 150s as a replacement for the earlier two models.
I did figure out the RJH-08 was the original one and read on the 2 different models, I also thought figured out that maybe I didn't have the original but what threw me off was the leather plunger I had inside. It seems like the short version to the 125s. But glad you clarified it is not.
Will the 150s bolt right up to my exhaust? Or would you suggest to go with the 136s? It's mounted on the bottom and not the top of the exhaust. Will I need to change out all the linkage or do you think it will bolt in and hook up as the one I took out. I can get you a picture of it if needed and maybe you can get me your info and price to buy that rebuilt one from you. I am also looking to figure out what motor is in there. Not sure if it has been changed either. Obviously a 6 but I think I was told a 215
Is there marking on it somewhere to clarify what it is?
The 150s is an updraft and looks the same as the 136s from the outside. It will bolt on your intake manifold. The accelerator pedal linkage should match up okay. The throttle and choke cables will need a different bracket from the one on the replacement carburetor which I also have.
There are casting numbers on the passenger side of the engine between the fuel pump and distributor on early six cylinder engines. The '29-'30 is 835501. There is also a casting date in raised characters. Letter A - L or month (A=January) followed by a space and one or two numbers (day of the month) another space and another single ending digit of the year. (9=1929, etc.).
If your numbers don't match the format or location post them and we can let you know what engine you have.
Hello Dave welcome to the interesting world of owning an antique Chevrolet. Not as many around. If you need some help with something this is the place to come. I have 2 29s now, and have owned one for almost 20 years. I am headed down to Glendale just North of you tomorrow to pick up a 28 chassis.
The carb you have looks like it is a tillotson. They made replacement carburetors for almost every make. Do not throw it away. You may want to refresh it and put it in the tool tray under the front seat. If it gets you home someday because the correct one gets gummed up with ethanol it will be well worth it. I keep a rebuild kit in my cars for the fuel pump as well.
