I just replaced the burrs in my Mazzer Mini. I am a bit confused as to the setting I now have to use to get a decent pour time. I was at 4 clicks finer than the "start here position", but now with new burrs I am about 6 clicks coarser than the zero point. Is this normal?

The "start here" sticker was specific to the factory-installed burrs. You'll need to repeat finding the zero point. Also see Fine tuning grinder setting with minimum waste for helpful tips.

I did find the new zero point. The new settings are relative to it.

IIRC, the "espresso zone" is around 1/8th turn from the zero point, maybe a bit further. Your grinder's setting sounds finer, but it may be a case of the burrs needing to settle in. If you have some old coffee, try running a few pounds through the grinder (30 seconds on, 1 minute off, repeat). For test purposes, I run 5 pounds of coffee through the burrs to eliminate flashing/swarf/oddness. See Is this grinder break-in? for more.

Thanks for the advice. I will give it a try. I would have thought that once the burrs have settled in I would have to grind fine, not coarser as the burrs would have become duller with use. This is the first time I have changed burrs on a Mini. I had a Gaggia MDF before and when I changed burrs I had to grind coarser initially.
This is what confused me as to the initial setting relative to the zero point on the Mini.

Thanks again for your help.

I don't recall the setting being predominantly one way or another prior to break-in. The symptom was a fussy grind setting, presumably because the particle distribution was meandering.
