Just make sure the pump has spec clearance at idle to ensure a reasonable stroke with no binding at the max travel. If you are concerned run the larger 6mm max spec gap with the big common idle screw backed out and recheck at idle, and adjust to minimum if too tight, that should make you feel better. It does not need the crude water pistol fuel pump squirting gasoline during very low throttle settings. I simply set mine at idle in the middle of the spec. range, been that way for years. There is also no need to readjust after standard carb balancing I have found due to the minute changes involved.
