By the way what does the lever looks like? I opened up the panel where the hop-up is and I see two gears. One large and obvious and one small one. I'm guessing I adjust the bigger one but it is pretty stiff and I don't want to break anything.
if you can't turn it one way its proly because its on full hopup or the other way around, no hop, you shouldn't have to force it, try turning it the opposite way it won't turn..
