Replacing my Mountain Bikes Front Mech

Well now that I have managed to change a bottom bracket on my Iron Horse Azure, I found the chain catching on my front derailleur and the shifting has started to be a bit slow chaning to lower gears, sometimes I`ve had to kick the shifter, not really a good idea. Also the screw for the L-limit is seized and due to the angle to access it the head has become some what worn. So I have decided to to replace it with a new one.
