This is a common complaint with Stromberg carbs. As you suspect, the issue centers on the fact that the Stromberg has no accelerator pump. It should not stall the engine, however, as long as you don't advance the throttle as fast as possible.
Chances are the float level is a little low or the idle mixture set too lean. A leak in the induction system can also cause this behavior. I've even seen carbs with the parting screws loose do this. Or, you could be advancing the throttle too quickly. What is "too quick" is quite subjective, though. It should be able to handle idle to full throttle in about 2 seconds. The problem is worse in the winter because the air is more dense and the carburetor correspondingly leaner. John
