Default NGH 17cc

Hi
I have a NGH 17cc gas and am having all sorts of trouble with this engine!!!
What does it mean when an engine backfires, while running at full throttle.
Have this engine in a Focke Wulf 190 60 size, runs great when on a test stand, but all sorts of burbling and not running smooth in the plane when in flight?
Someone told me at the field I should attach a velocity stack to the carb, I just don`t know.
What is the reason for the scary backfires at full throttle?
Regards
