I think I have an old RBS carb.  Let me check if it still has the rod on it.

It's the linkage. It's the fast idle cam and connector going to the choke leever. I feel the pump plunger assembly is a little stiffer.

My acceleration issue is fixed though it's just sticking. I took it off again to check for free movement but it seems to be a little stiff. Adjusted the pump delay spring to maybe compensate for the tougher plunger. Still getting stuck...

does it stick with the pedal linkage detached? eg is it the carb or the linkage?

Check the linkage for binding, and the spring for tension. You might just need a slightly stronger spring, or shorten the one on there now (if possible).

Rebuilt the carb. Only issue I'm having now is the throttle gets stuck.

Look through the service manual didn't see anything referencing stuck throttles. I might have to pull it back off but I should be able to fix it on the car.

Figured out what carb (4666s RBS Carter 1 bbl) had and ordered the rebuild kit. Fast shipping and great price for the kit.

Thanks to all those that helped.

I am loving this thread, learning a lot.

I have rebuilt one 1968, 199 ci. Stock rebuild. It had a Holley carb, never could get it to do right. I changed out to a Carter YF. I bought it from O'Reilys. Got a lot of info and parts from Mikes. Put a bigger jet in it and jumped my fuel mileage from 18 to 20 mpg.

The motor was in my 66 American convertible, The Rambler, now it is the power plant in Rapid Delivery.

My "new" 1969 American is an unmolested 199. I am going to check out the carb.

Having AMC Fun,
Ollie

Carter carbs had a three sided tag which identified them, that was attached to one of the upper bowl screws.  Yours appears to be missing.  If you contact Mike's carburetor parts with the information about what the carb supposedly was used on, he may be able to put together a proper carb rebuild kit for your part number.  There may also be a number stamped into the side of the throttle plate (bottom plate) on the carb which might have some chance of being unique to your carb.  Joe

Any ideas? Don't see any other markings on it.
