I've got one of these, do you find the revs drop of once you take the glow off ??, another good sign it's a bit rich at the low end. Just follow advice above and you shouldn't go far wrong.
All the ASP four strokes I've had were all a tad rich on the factory bottom end setting. Whether this is done to be a bit on the safe side, I don't know.
I own several ASP motors, 2 & 4 stroke. The four strokes need to be a little rich as they have a reputation for running hot. Oddly, they need a "hot" plug to run successfully. I always use the Model Technics F7 (actually in ALL my engines, regardless) Try one of those and not too lean on both needles.
