start by cleaning your jets even a small piece of dirt or gum can clog the idel jet
two sloted screws on front and back of carb NOT the ones with the springs those are air bypass screws leave them alone for now.
also see if you can find any air leaks around any of the joints up to the head, carb cleaner should work but be carefull
the samba should have several articals on tuning a weber progressive
tuning is not to bad its jetting it that takes awhile
they are notoreusly over jeted.
if it aint broke, break it then fix it
