Well I wanted to play this weekend at the Charlotte game. So I recently opened my gun up reshimmed it put a PDI 130% spring in it. The gun is a JG M733 C. The noise comes only after shooting full auto for a second.
After shooting full auto the gun makes and extra winding ( something similar to a zipper zipped up) noise even after your not pulling the trigger. I was trying to tune the motor and I followed a guide off of airsoft retreat maybe it could be that. I'm really confused and desperate to figure it out. Thanks for any help in advance.

You forgot to put in the anti reverse latch. That sound is the gears going backward.

The latch is the one located next to the bevel gear right? If so I made sure that it was working properly. I tried to turn the gear backwards with a screwdriver but it would not go. Is this sound possible by anything else. My BB's are coming out weird and now the sound happens on semi auto too. If you think its just the latch I can open it back up.

Definitely open it back up... you may have shimmed it incorrectly and that sound is something to do with gears grinding (not good). It could also be motor height, but that doesn't seem as likely considering the fact that it still fires fine.
But yeah my first thought would be anti-reversal latch since it sounds like the gears keep spinning after you shoot on full-auto.
Either way, definitely check it out.

You couldn't spin the gears backwards because the piston was already already all the way forward. When you put the box together, the latch has to have the flat part sitting against the bevel gear, not the rounded part. It's an easy mistake to make.

Props to Kiki and Gestapo. Thanks for helping. I played the REC game around me and the Canto and Tex said it would be fine for about a month.
I opened the gun up today to discover that the spring that applies tension to the Anti-reversal latch was off its track. Fixed that and now it does not make the noise any more. Just thought I would post a fix update. Thanks again.
