only thing i can think of might be a tendancy to richen as flight speed comes up due to increased head pressure felt at the needle

It can work very well. You can set the engine for max power for takeoff, and then it'll richen up a bit for level flight, leaving you with some reserve for maneuvers. It should not be set up with "ram air". That can lead to too much richening in level flight. If you're using a uniflow tank, be sure the uniflow is in some neutral area, like near the backplate of the engine.
