i am having a problem with my CPA action. The only way the hammer will cock is if I pull back on the back trigger as I cock the hammer. Then it cocks and the set trigger works as normal. As I watch when I pull back on the rear trigger to cock the hammer I can see the sear drop down (from the back view) and then the hammer will cock.  All was working fine and then just started this problem. Any help would be appreciated. Getting ahold of CPA is more difficult than calling the president.........thanks in advance

The thingy on the hammer (called a f-ly) may be burred, battered or stuck so it doesn’t allow the sear thingy to catch the full thingy notch.  Take the hammer out, reinsert hammer and fly on the hammer pin and examine to see if it moves easily up and down in the hammer s-lot.

Wow; automated Internet censure algorithms are getting so efficient that soon I will have nothing to be Offended about.  What’ll I do?

They answer every time I have called and respond to emails quickly

Ok, so I'm laughing about the "thingy" deal, but curious how I vote on this "poll"?

I guess then, that we can't say "until the hammer has intercourse with the sear"? How about "engagement"? "intercourse" might be OK after "engagement", no?

Well, I don't know much about the CPA rifle, but I doubt that you can fix it by spraying 'break' cleaner on your thingy. oneatatime suggested doing this, and if anybody tries it, I'll be surprised.

Mr.card1 does your CPA have the through bolt if so there is a fine line of getting the triggers to work properly based on the tension of the through bolt itself. The way it is designed it can actually put to much tension on the bottom tang and bend it just enough to where the triggers will not work properly. 
One other thing to look at is the spring putting tension on the back of the sear block. I have seen it slip off to the side off the block. Mine came with a piano wire spring and it would do this from to time to until I cut a groove for it to rest into and that was my own fix.
I highly doubt it is the fly giving you issues and if turned around and not installed properly it just wouldn't go to the half cocked notch when opening and closing the breech block.  
What is also interesting is when I tried to use half c__k instead of cocked it automatically changed the word to thingy ?

Three things come to mind for me.
1. It sounds like you have the stock off since you can see in the rear.  Is there a spring on top the rear arm of the sear?  It is attached to the first screw behind the frame on the lower tang.
2.  If you have messed with the trigger/lower tang screws try loosening the front one just slightly.  If the sear fits well in the tang it can be bound up by a really tight front screw.
3. If you have the stock off remove the trigger assembly and really clean it out and oil as has been said and make sure everything is moving freely as they should.
