Question about maintaining a spring assisted knife

I have a spring assisted knife made by ProTek USA, and when I open it the spring doesn't work at all.
It used to flip out smoothly and quickly, now it's basically a knife with a thing to partially open it and then I have to pull it the rest of the way. I have already tightened/loosened the nut/screw at the pivot of the blade, that didn't do anything. It is well oiled, so I don't know what else is the problem unless the spring is broken. Any help would be appreciated. Thanks.
 
ProTek knives are very cheap, so you shouldn't expect a high degree of quality or long life from them. Cheap assisted-opening folders are very prone to failure, expecially problems with the springs.
 
The spring could be simply worn out. Kind of like how Kershaw says their speedsafe springs have a life expectancy of roughly 10,000 cycles. I had a 1950 kershaw tremor where the spring simply snapped mid-flip, and on my blur it just got slowly and sluggier until the spring was dead and needed replacing.
 
Do you have the tools to take the knife apart? I would check the spring, I have no experience with ProTek, no idea if you could get a replacement
