either lost the nib or not lined up the hole in the hop

did you loose a very small clear tube- like a section of the inner part of a biro?

often happens, its called the hop nub

i really dont know ??

[M_P]

well could you take it apart again and have a look maybe?

If not, send it to a gun mechanic or gunsmith etc to take a look,

before you send it away, remove the hop and barrel, look down the barrel hop end and while turning the adjuster see if you can see the hop rubber being pushed down, if u can then thats not your problem and could just be a air seal fault, if you cant strip the hop down again, and see if the nub is in the correct place, it should be on the bottom of the hop arm, also on the barrel is a slot, the hop rubber should only slide on one way due to the groves, but the slot needs to line up with the nub/hop arm
