Engine stalls going over speed bumps

I can check on that, I did take it to a mechanic that works on carbs and engines, as well as races himself and he set the carb up at least by ear anyway. It idles nicely and doesn't seem too low. I need to get a tach gauge to check the difference when switching from N to drive. I just moved the car to Houston where I live and I don't have any tools with me yet...
