Front Derailleur Adjustment Screws

I had my *first* ride this year today, and my *first* ride on my new bike.. Was fantastic!

Had one problem though; when I changed from the small chainring to the big one – if I pressed too much on the lever the chain popper over the edge -.-

Have a feeling the derailleur is simply pushing out too far.. Which screw is it again to restrict the *outwards* movement of the derailleur again? Inner most, or outer most?

Its a shim 105

I am asking here because I am too lazy to go out in the garage and check before I ride tomorrow 😛
