Well most gassers DO hit close to full power with the throttle butterfly about the halfway point, not much left in the last bit of travel. They are also really sensitive coming off idle and the combination of those two is why you see folks talking so much about throttle linkage geometry as well as some use curves to help give you either a more centered throttle stick at half engine power, or achieve a better control of low RPM situations, or both.

There are also several other tricks you might want to try, check the forum threads with the search engine for more ideas....
