Hi!
I have exactly the same problem as this video:
Airsoft AEG: Tappet Plate and Air Nozzle Troubleshoot - YouTube
I've been looking for the answer for quite a while but I can't find one.
I've already tried 3 different magazines but still wont work. I've also installed a delayer chip on sector gear but still no luck.
My tappet plate looks solid and not yet broken. Nozzle is also fine.
I don't know where else to look.
Please help.
