What do you mean push the switch? I cant run the motor unless i leave it in the gear box, sorry i`m new to most this. Hmm my shimming is pretty good, after doing it 50 times alone on this thing, it fires then after i let it sit usually for a day or a few hours, i go to fire it and it`s locked up. The gun itself has been hardly fired. Ive had this lock up issue since the second day of having the gun, bought from Evike. I`ve maybe put 6000 rounds if that through it.

Take the motor out of the gear box, but leave the wires attached. Press the metal bar of the switch while holding the motor and listen to how it sounds. When it locks up, does it just make a clicking sound? Or is it winding back and then doing nothing?

Motor runs fine, not sure what to listen for, but ran fine, and yes when it locks up it makes one click noise when i pull the trigger. It didnt lock up when i just ran the motor in my hand

If the motor is still the stock silver unmarked casing then that is your problem. It has barely enough torque to pull the stock spring even with good shimming.
After all the years of dwelling in stuff like this my own personal conclusion is that A&K is piecing parts from different supplier just like any other ACM company and in this case they simply get the parts spec wrong in this build. The silver unmarked casing motor is design to be use with the older gen Chinese AEG which usually comes with softer sping that shoots about 350-380FPS range few years back. But then due to market demand many Chinese company start using the higher tension spring which tends to end the gun up at 420-440 FPS stock and those should have been usually using the little more torque type black casing regular ferrite magnet type motor like the one in the M249 or the Neodynum magnet type high torque motor. However in this case I think they are either cutting cost down on the cheapest motor they can source or just parts planning/spec'ing incompetence which ends up with the current spec.
Swap the silver unmarked casing motor out for a better motor like Matrix Magnum 3000 type or any other Neodynum magnet type high torque or high speed depends on your firing speed likeand you'll be able to pull it with even 7.2v NiMh battery pack(yes 7.2Volt not typing error).
As for the list of your problem I'll probably address it in a day or 2 because of time constraint now sorry.

Thanks Casper, and yes it is a greyish silver unmarked motor and it would explain why it keeps looking up no matter what I do. I`ll try to get a motor, but probably wont be soon, and no rush on addressing the other problems, it will take me a bit to repalce any parts as is and atleast, i think, it`s safe t say my constant locking up issue is explained, but why would it then fire some times, then randomly lock up? Thanks again Casper and The End for all the help, definatly slowly making progress.
