Tippman Bravo one not re cocking.

[csdude]

Hello all,
I have recently purchased a second hand Tippman bravo one.
On the test fire all was good and it cycled fine, the gun was quite dirty so I took it apart and cleaned and re lubed the internals and put it back together.
viewing the reassembly vids on you tube I seem to have put it back together ok however after I test fired it after the clean it seemed a problem had developed.
I was firing and after every few shots the bolt doesn't come all the way back, I have to manually pull the bolt back and fire, it is then fine for another few shots and then the same thing happens.
Any thoughts on what I have done and how to remedy this would be appreciated

i had a similar problem and i found the ASA was partially blocked, i would check its all clear the air is getting through without an issue. it might not be the case but worth checking
