Crosman Tac R71
 

This week, I obtained some older model airsoft guns, literally all but one were broken, I got a crosman tac r71 in the lot, it would fire, you could see the motor kinda twitch(?)
I took the whole the apart, the gears got misaligned so I realigned them and I got it to fire but there's a small plastic piece that the trigger itself pushes to activate the motor but I can't put that and the spring that's on it to go into place, I should have taken a picture to show myself how it all goes in but I wasn't thinking, anyone able to help?
