Three options:
1-Lower pressure range (this will make the influence of the self-controlling properties of the engine more pronounced because carb vacuum can play a larger role)
2-modifying needle taper while maintaining original thread (this will leave slop in the threads unchanged and might make the needle less critical but does nothing for accuracy)
3-finer threading (IMHO best option because it will also reduce slop and make settings also more constant)
