tuning ya cocker
now ususally that reason y u need to tune your cocker is if you get a new trigger or pnuematics. correct?
if you got new pnuematics then you need to turn the timing rod
(the rod from the trigger to the 3-way)...youll notice the change i you shoot the gun... a good way to know ur cocker is timed is to put a piece of tissue up to the feed. a well time cocker should suck the tissue clean thru the gun. (if the barrel is off that is)....
or remove the bolt take an allen wrench and adjust the hammer lug so that it is overlaping the sear
thats about it...if not take it to a professional..if they charge you tell'em ur broke...lol
good luck
