Wow! Nobody?
So we decided to jump in with both feet! I found an exploded diagram of the gearbox so I had some reference if something was out of place.
The box was a bit of a pain in the a$$ because you can't split it without disconnecting a motor lead...and the motor leads are soldered! And of course my soldering iron is dead, so I had to buy a new one. We eventually got it apart, cleaned everything up, replaced the o-rings and greased what looked like it needed it. Got it all back together, and test fired it. It seemed to be working fine so we reassembled the gun and tested again. It fires OK and feeds OK but we haven't been able to test accuracy and velocity yet.
Now the problem we have is that it sometimes fires a 2 or 3 round burst in semi auto. Looks like we are going to have to go back in
