FAS 606 trigger problem

[johnd232]

My club has an FAS 606 which has been left for several years in the club safe. On enquiring within the committee why it was not used I was told it didnot work. I have just taken it apart and find that it doesn't work as the trigger components are not all in contact when the pistol is cocked. I could use some information on setting up the trigger to save me hours of experimentation.
