Rusty you can see the broken piece in the picture. Its the piece that goes on the throttle shaft and actuates the accelerator pump. The unbroken version is visible in the picture you posted. I tried a JB weld repair last night that may or may not work.  I'm going to try to find a screw to replace the missing one, make some proper throttle linkage and fab a better fuel line today. The air cleaner adaptor is going to take some head scratching but I'll figure out something.

Strange thing is that this BB-1 starts cold without using the choke and even without a working accelerator pump doesn't hesitate. The choke cable will hook up but is really too short and doesn't work very well. If I stick with this carb I'll fix that. 

Laugh at my emergency throttle linkage if you must but if it works is it really a bad idea? 

Great pictures Dave. It's good to have you coming around again. Videos would be good too. I am still looking for some hood latches (both pieces) for our 29 Touring and I still haven't figured out anything on wipers but I haven't tried very hard. 

Thanks for the pictures of the adaptor and your BB-1 Tom I don't guess I know what LAS stands for.

I checked the float carefully today and as far as I can tell its fine. It doesn't sound like there is anything in it when I shake it and there is no places on it that look compromised. I even weighed it then held it under water for several hours and weighed it again with no change and no bubbles. It weighs 0.80 of a ounce. Here is a picture of my emergency install of the BB-1 of unknown heritage. From what I have read its a later version with the pot metal bottom so I doubt it came off a 4 cyl. I'm making what is probably a futile attempt to fix the broken piece. It's also missing one of the screws that holds the two parts together.
I may call the Carburetor Shop people in Missouri and see if they have any ideas on the RT-08 but if I can fix the BB-1 it may be the one we run and the RT-8 may get put on the shelf (but I still want it to work)

I'm going to check the float over carefully tomorrow as you suggested. I was so frustrated with it acting up right before the show that I didn't examine it very close although I would have noticed if it was very heavy or sloshed. That is the only thing I can think of. Today is Sunday and I try to not do much.
Russ T. I was impressed with the BB-1 and will be trying to find the broken piece and a way to put a air cleaner on it that looks somewhat correct. Do you run one? I'll post a picture of the broken piece tomorrow too.

The day before our big car show the car died on my wife but she got it running and nursed it home. The brass bowl Carter was flooding big time.

 Back story is the gas tank had developed a small leak and had I pulled it off and discovered the baffle was completely broke loose and just bouncing around in the tank. I cut a hole in the top big enough to get the mig gun in then cleaned the inside of the tank and welded the baffle in. Then I had my son weld the piece back in the top (he welds for a living) then sealed the tank with KBS sealer using their kit and following the instructions to a T. The sealer dries hard as a rock and the fuel coming out is now completely clean.

Thinking I had got something in the fuel line when I pumped the tank out that stuck the needle valve I took the bowl and float off. Nothing not even a speck. Put it back together and no improvement. Took it back apart and lowered the float level, no improvement. I took it off and hooked a long fuel line from the pump to it and set it over a bucket with the bowl off. It works as it should, spraying gas out of the needle and seat when I let the float drop and when I gently close it it shuts off the fuel. I checked the fuel pressure and it has less than 1 lb.

I finally gave up and put on a Carter BB-1 that came with the spare motor I bought. It looked pretty bad and the accelerator pump linkage was broke making it inoperable. The hole for the linkage was smaller so I made a very crude one from a piece of bent 3/16 brake line just to get it to the show. It fired right up without even using the choke and runs good. We made the show but now I want to figure out what to do to fix the brass bowl carb. Any ideas? I have worked on everything from  Quadrajets  to a tea cup Holley and have never found a carburetor I couldn't make work.... until now!

Oh I also tried taking the gas cap off incase the now 100% sealed tank was building up enough pressure from the day warming up to overcome the needle & seat that was designed for gravity feed from vacuum tank fuel pump but it made no difference.

Any ideas?

If you are being judged by POC standards and they can't tell you what was original how are they going to say leather is wrong! Personally I would use one of the leather lookalike materials. They are hard to tell from leather and hold up a lot better. They are also less expensive and easier to match and work with. 

I bought discs from a vendor (Pm me if you want to know who)  and when I installed them they didn't seem very good but the seller claimed they were the best on the market. They ran about 20 miles and then came apart leaving my wife setting in the middle of the street with the shaft wedged against the floor! I had to remove it before we could get the car out of the street. I sent him the pieces and he begrudgingly refunded my money claiming he would sell no more discs. I bought another set from a different seller and so far they have held up fine. Make sure you have washers between all the discs and between the discs and the spider so they can flex. And yes they vibrate some at speed but smoothness isn't our cars finest virtue anyway. Picture is what was left of the discs from the first vender.

Sorry the DT in my above post was a typo. Our car has a RT-08. It has the short accelerator pump.

Hey Tom what's the difference in the RT-08 and the DRT-08? I have seen both listed for early Mopars. Our car has a DT-08. Its missing the little cup fitting that the fuel line is attached to. It has the line clamped to the nipple that sticks out. I know that's wrong but I haven't found a good fitting or screw. I'm not sure if the threads the screw threads into are good or not.

The cap on our car looks like the one in the picture except it doesn't have the depressions on top its just smooth with the fin in the middle. I have no idea what it came off of except I'm pretty sure its not a 29. I think this is the 29 cap. I would like to find one but I probably wouldn't pay what they would want if I did.

Cheap? Too much? I don't know I just saw it and thought I would share. If it was for a 29 it would be a good deal.

I hope the forum picks up too. I have been working feverously or at least for me on a late model car (compared to our old Mopars) since I spent most of the summer working on the 29 and its running good. It still needs a lot of little things done so it will be back in the garage in 2024. I will share a picture of my newest project just to get some content going. Don't hate me.

Same to you! Lets get this forum going again. We need it.

The old girl ran perfect. All the work I did last summer was worth it to see her enjoy her car so much. The parade was Saturday night. Sunday we took our neighbor his wife and two young kids riding around then Sunday night we drove it to church and gave our Connections Pastor a ride. He is struggling with stage 4 cancer and was told 5 years ago he had maybe 5 years to live.
