Single Barrel Carb woes

Two cans of carb cleaner, a bottle of essential lube, some misguided tinkering, and alot of "rev-tuning" in the garage so far has resulted in.......an engine that will start and run very rough with the choke in Fast-idle, and dies as soon as the fast-idle drops off.

The Carb has a Red nameplate that says AutoLine products LTD. C-606.6 Remanufacturered in Canada.

I can't seem to find any information on this carb and wonder if it's actually a Carter that was rebuilt and rebadged. I've tried to find carb rebuid kits for it but none of the parts stores here have any reference for that part number. Google failed me to, although I was able to find Autoline products in Canada, but they offer no information about thier products and I'm assuming this is not a recent product of thiers.

As much as I'd love to just replace it with something larger, my plans for the car ultimately involve more than a couple of bolt on's so to keep it driveable in the mean time I'm hoping to restore the use of this carb.

Any ideas?

 

Post good clean picks, I just rebuilt my Carter single barrel, see picks below.

Here are three different angles....

 

Trying to find a Heat tube for the choke. There has never been one since I've owned the car.

 

Thats a Carter, I may have a heat tube, when it stops raining I'll look.

 

Any idea's on a part number for the Carter? Electric choke and carb rebuild kit are the next things I plan to try. There was a Carter rebuild kit at a CarQuest near me but it referenced a specific Carter Part number. Maybe there's only one???

 

If I remember correctly there are three diff. kits for the carter carbs, any other numbers on it?
one is for AMC one for Ford and another for Jeep it's a Carter RBS and here are the three diff. kits offered for it.......CK40 ... CK570 ... CK571

 

Its a carter rbs as stated the rebuild kit is the same as stock my 73 has the same carb kit was 11.00 at autozone.

 

And you have a ported vaccum port connected to a manifold vaccum port causing a vaccum leak into the venturi.

Top port on side of carb to vaccum tree on intake is a no no


And the heated choke port is another vaccum leak plug it


And make sure the egr is hooked up correctly it should not see vaccum at idle

 

Yep, Carter RBS. http://www.carbkitsource.com/carbs/tech/Carter/RBS-index.html

Argh, any suggestions? Having a hard time even identifying what this is. I think it's the (OK, here's me showing just how little I know about this stuff) the saucer shaped part with a single hose, mounted to a casting that bolts to the lower portion of the carb base???

I did notice that when running, there's a substancial hissing sound that was not there before and it seems to be coming from said saucer shaped part. If I pull the vacum line while running, the engine definitely changed pitch a little. hard to tell if it was for the better or not due to it running so rough in the first place. I thought about caping this line off entirely just to see what happened.

Should I just cap it?

Thanks, was about to buy an electric choke....but throwing parts at a mystery is starting to get expensive.

The frusterating part is, this car has been driveable for the past year. All of a sudden, mid-trip to the store, it just started running rough and would not idle.

Feels like I am making progress. Definitely learning alot more about my car.

Thanks for all of your help.

 

Yes cap both side, and the egr bolts to the carb base you could try tapping the egr with a small hammer and see if the idle improves it could be stuck open

 

This will help also http://www.carbkitsource.com/tech/Carter/RBS/RBS-CK571.pdf

 

Starting to think my EGR valve has something to do with my problems....

Found this short video on testing and EGR valve and according to the video, my EGR valve it toast.

So, would a failed EGR valve cause the engine to die as soon as it drops out of fast idle into idle?

The engine starts and runs ok with the the fast idle on.....but the second it drops it's like someone turned the ignition off. If I catch the throttle linkage in time I can apply a little throttle and keep the engine running.

After plugging the choke heat tube port and the top vacume port on the carb and vacume tree the engine runs better when fast idleing so there was some improvement....but it still won't run at idle.

Feels like I'm making progress though, entirely thanks to this board. Thanks for all the help.:Handshake
