starts but won't run

[700rpm]

I suspect a fuel problem. Make certain neither end of your fuel line is pushed too far in, which would restrict gas flow. Also make sure your sediment bowl is not full or clogged.

Ray, I’ve been told by several different members that the fuel line ( in my case, fuel lines) could be pushed in too far, but I don’t see how. I’ve attached a photo of the front carb because I’ve got the back carb diconnected from the fuel line with the choke wired all the way closed. I’m hoping that if it is a carb problem I can get it running on the one and work from there.

I appreciate your advice and wish I didn’t live so far away from someone who really knows A’s.

Thanks again,
Mike

Answering the question in post #7 could possibly help with diagnosis.

are you saying you have two carbs? If so it is another ball game.

The car came with the dual Tillotsons, and the previous owner never got it running for more than a minute or so. I have the original Zenith and manifold and both are in good shape, but I’d like to get this thing running with the Tillotsons to see if they actually add 10 hp. If you really feel that this is a carb problem, I can put the old Zenith back on. Those Tillotsons look really good, but are worthless if they won’t give me a smooth running engine.

Maybe that would be a good starting point just to see if the problem can be isolated to the fuel/carburetor system.

Besides, if you don't have the original to compare the dual carb to, how will you actually know the difference?

I agree. Put it back to stock with the original carburetor and manifold and get it running well that way. Then you can tinker with a different set up. Too many variables this way trying to get a car to run for the "first" time.

You will have to get both carbs working together if you want it to run.

Blocking one carb off does not mean it will run on the other.

Even though the manifold may have a cross-over tube that is more for balance than to allow it to run on one carb.

I have a dual carb MGA and if one carb drops off for whatever reason it will just barely run on the other if at all. It too has a cross-over tube between the carbs.
