CYMA MP5 Full Auto Issue
So a friend of mine recently purchased a CYMA mp5 and after 3 or 4 games it's begun to only fire 3 or 4 times on full auto and then cuts off. No telling sounds after cut off, just silence.
It's due for a dissessembly and a tune up but I am fairly new myself and only worked on my v.6 and v.3 gearboxes.
Can anyone tell me what to watch out for, and what could possibly be causing such an issue? Thanks!
