Yes and no...i got it adjusted to the point where the pedal will bottom out about 1/32nd short of opening to WOT (that way, there is no extreme pull on my throttle cable when I gun it, but all the power is there)
If you're having issues the first thing to check is pedal movement
Is there anything keeping the pedal from going all the way down, or all the way back
If that is clear, check for adjustment in the cable itself (if it is stock, you can adjust the outer sleeve where it mounts to the engine)
Finally check to see if you have the correct linkage on the carb
Worst case scenario you can move the connecting point on the throttle arm closer to the shaft, changing the geometry and fixing if that way
Toss some pictures up of the engine and who knows, we may spot something obvious that you're simply overlooking
