CTW help

[Ekko]

Asking for some help with my Celcius ctw. First off, is it even worth fixing? Bought the gun used after being sat in storage for a couple of years, managed to get it cycling a few times but the motor got very warm after a few cycles. After a few months of not touching it the gun now doesn't cycle at all. Had a mess with it but the things like a rubiks cube and I have definitely made it worse trying to use my 3 brain cells to fix it.

If anybody with knowledge of these guns could lend a hand or direct me to somebody who may be able to help it would be greatly appreciated. Really don't want to see this gun go to waste.
