TSS Power Problem
I don’t know what’s going on, but I can be shooting a while, then all of a sudden the gun seems to go into “no power” mode. The shots fall off about 5 inches and it doesn’t sound like all of the air is coming out of the tank. It sounds like I threw the pellet at the target, no solid CLANG on my pellet trap. Tophat is in stock position and I’ve tried moving pwr wheel all up and down but it doesn’t help. Any ideas?
Thanks

How’s it shooting since you adjusted the tophat forward to close the gap? Are you still getting dud shots?
Would lowering the Power Wheel help? Seems if you moved the TH forward, you would be able to lower the power wheel and compensate. Does it work that way?
I called Airforce to get their take on the situation, and they also suggested that I just adjust the tophat forward until the breech fits snugly when cocked and turned to either side. So now my TH is set at .14. So much for being able to adjust the gun for power and efficiency with the TH.
Yes, with the rifle cocked, the breech has some movement in it even when turned to either side. All the way closed and pushed left, I can still move the breech up and down the width of the set screw in the tophat. In fact that’s how far down the breech goes, to the bottom of the set screw. When it’s not cocked, it sits tight against the TH. The tophat is adjusted back to stock, about 3/32’s” or .09. Also, when I push the breech forward, it seems to be binding a little just before it goes all the way up.
Even though the TH is factory, should I adjust it higher to get a tighter seal between it and the breech? Is there a limit to how far up the TH can be adjusted? I thought the whole idea with adjusting it was to get it down as far as possible to get better consistency and more shots. Or, instead of adjusting the TH higher, is there a way to adjust the slack out of the breech so it fits tight against the TH when cocked?
Thanks
There shouldn’t be any movement between your knob and the frame once cocked and pulled back against the tophat once the knob is locked by pushing it over to the side. If you get movement, even a 32nd of an inch, it is most likely your problem. If there is the slightest amount of gap between your tophat and breech when you fire, you’ll get a low velocity dud shot. Either your tophat needs to be adjusted out or the o-ring that rests against the tophat when the breech is pulled back against it is worn. This happened to me.
Maybe your hammer has a bad spot, causing it to fly back slower sometimes?
If you add any grease or other lube to the hammer, it will vary velocity a lot.
Any time I’ve had velocity changes, it was usually because the hammer wasn’t all the way back. I also had issues with the breech knob binding in the slot before I made a new one.
I noticed from some of your previous posts you may have your tophat adjusted very low. As the pressure in your tank decreases the tophat will need to open further. Yours may be “bottoming out”.
I pull the breech back as far as it will go. I’m figuring it has to have something to do with the valve not opening all the way, but why, I don’t know.
Thanks
I pull the breech back as far as it will go.

Everytime that has happened to me it is because the breech is not pulled back against the tophat. When the hammer hits the breech it must be in contact with the tophat or you lose a lot of power.

To add to Varminters questions. When you say “shooting for a while”. How many shots are we talking about?
