broken or sticking tip?

[jon103a]

hi, hope someone can give me a little advice please, i have a 92 fd which has been running fine at 360bhp, had bigger injectors uprated fuel pump and a few other bits done and remapped still at 360bhp by pip, was running really rich though, a 100 miles or so later it starts to run lumpy at idle and gets worse, front rotor now has low compression on two sides at 7.3/3.5/3.5.
thought oh bugger its broke. been looking on the forum and seen someone saying they might have a sticking rotor due to theirs running rich - is there any way to tell if its broken or just sticking and will a good thrash help to unstick the tips or any treatment that might help. many thanks in advance, jon.
