ok yesterday i was timing my cocker cause the peice that is suppost to be in my 3 way fel out so i put it back in and i had to re-time it. and this was my first time timing a autococker. so i went and timed it and i went outside to see if it was working right, and i pulled the triger and it was leaking so i pulled the trigger and held it and leaned over to see if the leak was coming from my 3 way, and i had the back block leaning against my chest and i listened to see where it was coming from and it was the 3 way so i backed my head away and i still had it leaning on my chest and i let the trigger go and the back block slammed forward on my nipple 
so i had to pull the trigger again so it would let go of my nipple and i have a red bruise and it hurts really bad. so i went inside and unscrewed the set screws off the 3 way coupler that is on the 3 way (timing) rod, and turned the 3 way coupler counter clockwise a couple of turnes and put the set screws back on and went outside and shot it and it was perfect.
