Can someone explain to me   why when I make a hard left turn from a stop, the engine initially starts pulling  strong but as I keep turning it starts to cough and sputter.Like it is fuel starved .I have no such problem when making the same kind of turn to the right  !
These are stromberg carbs btw.

cough and stumble should be fuel system, float level or line blockage although my experience with stumble was usually too rich.  how are the plugs?

I haven't checked the plugs ,I will do that .
Wouldn't the issues you mention float level and line blockage  affect straight line running and right hand turns as well ?

Or am I over thinking the problem ?

Think of what happens when you turn left. What happens to the car? It dips a little to the left and the right side rises a little. Just the opposite when you turn right.

I'm with Dan on the cause. Fuel related. Time to check the floats and level of both cards. Could be one of the floats has a hole causing a difference in the height because of the added weight. The floats are out of adjustment causing an issue when you turn left.

Is the fuel level low in the tank? Had this with a Maserati where the fuel take off got exposed as it was to one side.

Tank level doesn't seem to make a difference  ,I never let it get below 1/2 a tank ( don't trust the sender below that level )
Is there a Maserati available that I could test out your theory with ;-)

It is not usually the fuel tank  since there is so much fuel between it and the carb.  More than likely it is in one of the carbs.  When you read the plugs the darker ones will probably be the problem.  Spend some time reading up on the "stromberg cd175"  by googling . there is a lot to read. a high fuel level in one carb might be the problem.  My Webers still break up under hard lefts /hot engine, but  a notch leaner on the low speed jets should solve it.
