Sure. I know exactly what the problem is. I race a TR4 and it had Strombergs on
it. I was determined to make them work. I got the car to really haul down the
straightaways but for four years I had the problem you describe. I finally 
it out.

The pivot for the floats is on the right hand side of the carbs. That means that
when you make a left hand turn, the gas sloshes to the right, the floats drop
down, and the fuel pump pumps gas right through the float chamber and out into 
throats. The engine goes rich and will hardly run for a few seconds. Very hard 
detect, because even an exhaust gas temp gauge won't react quickly enough to 
what's happening . The mixture corrects before the gauge will respond.

We tried everything we could think of but never overcame this basic design flaw.

We solved the by going to S.U.'s. If you come up with a way to fix the problem
with the Strombergs, I'd sure like to hear about it, just to satisfy my 
I'd also apply it to my street TR6, which does exactly the same thing.
