Thanks for that Im assuming that you simply adjsut the barrell nut down until free play is gone when cam is on its heel plus a 1/2 turn and then turn the internal grub screw within the barrel nut down to set the barrel nut tight, is this a correct assumption, Ive read on a couple of forums of people having to shim the main posts ect and couldnt work out why they would do this.
Any response is appreciated Thanks
