I had that with my STO mech cocker. in the end I got Jack at Planet to drill a hole and put a self tapper in it that held the rod in place flush with the body. Think it cost me about £20 inc the p&p...
dont suppose anyone has a lil grub screw to go in that timing rod, as my mate only has the one! Ryan, will get it posted off to you soon! if the whole grub screw thing isnt enough to sort it!
