carburetor problems.

I don't know much about cars, and my dad doesn't know much either. I just bought my first car about two months ago. It's a 67 dodge van. Windows and long wheelbase. Automatic and 225 slant six. It's in alright condition, but now it's running pretty bad. I'm pretty sure the problem is with the carb. On acceleration, the engine will stall if I don't have a real light touch on it, and even then it will feel like it's about to stall. When I first got it the throttle seemed like it was sticking and when we looked at the carb the spring wasn't pulling the throttle thing back, so my dad threw another spring on it. Since then when I first accelerate it feels like there's uneven pressure when I push the gas.
I'm pretty sure I should rebuild the carburetor, but I don't know what model it is. It says on one side that it was made by Carter, and on the other is the number 6 5075. I searched for it online and didn't find anything. It's a single barrel. Am I looking in the wrong place? I was also wondering about the differences between carbs and whether it might be better for me to get a new one. Would a 2 barrel be better?

Actually the number is 6 2072. Reading on mirrors can get tricky. Still can't find anything though. If there's anyway I can fix this today I might drive it to that Council of Councils thing going on tomorrow.

Just checked that out and didn't see any gas spraying or anything. The other day my dad and I were looking at the carb and were trying to figure out what the accelerator pump was. It didn't seem like it was doing anything. How would Go about fixing this?

If you have no one that has experience and can teach you, I'd suggest paying for the service.
Have the carb rebuilt and a complete tune-up done (compression check, valve adjust, points, plugs and condenser) and 'scope it out to see if the cap, rotor and wires need replacement too.
It would be a good time to replace the oil and filter, the coolant if it's not in good shape, pressure test the cooling system, and do a brake inspection.

Any time a person with little or no experience buys an old car, there is a period where it can become a beautiful experience or poison that person to old cars for life. While I can usually describe a basic procedure fairly well, if you have no background and no one to help, it will probably turn out badly. Better to get the van in good running condition and learn from there.

I get what you're saying about getting help. I kind of like doing things myself and would like to figure this out. I've already replaced the rear wheer cylinders and master cylinder which was a bit of a struggle since I didn't have a clue how breaks worked before that. I don't know if rebuilding a carb would be out of my league, but I feel like I might be able to handle it. I have some neighbors I can bug when I get stuck.
It seems like the rocker arm is working, but it doesn't move the pump. Pictures might help, but I don't have a camera right now.

Might I suggest connecting with other members in the OC, enrolling in a community college course for automobiles, and otherwise emmersing yourself in the rich Southern California car scene?
Help really is around almost every corner, and the basics are usually shared with gusto.


There is a reason these signs are funny!

And you got the smaller leading shoe on the front on both sides, got the self-adjusters to work properly, and bled the system? GOOD JOB!!
Many have been stuck on brakes. If you have the mechanical apptitude to handle that, keep learning and ask for help when needed!

The biggest problem I had with the brakes was getting my driver side wheel off. Didn't know they had reverse threads.
I can't seem to find a rebuild kit though. Any tips?

I'm pretty sure that I do have a Carter BBS, and from what I've learned is that the carb number should be on a tag. There's no tag to be found on my carburetor. I have some free time to do the rebuild, but I can't figure out what parts I need.
I think I'll just be taking it into a shop. I'm sure they can figure it out. Does anybody here have any recommendations for places around Huntington Beach/Westminster?

Another big thing on BBDs is loose/worn throttle shafts.
This is about the easiest carb to rebuild there is.

or take it to the auto parts store and get a rebuilt carb.
