I've got CA33E spit out 2 BB at same time when it's on single fire mode. Does any one know about this problems ? Please help. :(

There could be a few different reasons its spitting out two bb's,

*waiting on someone to jump on the fact that gun nut mentioned gear timing*

soo?

Could you please explain your theory in gear timing???

heres the theory, if the gearbox is mistimed slightly the tappet will retract longer than it is suposed to which will result in multiple feeds, or not but my gun worked after i fixed this,

well heres a fact:

good point, if thats true it prob wasnt the timing that was screwing my gun up, maybe it was just in need of oil or mishimmed

I cleaned up hopup unit (metal) inside out and then drop couple silicon oil in put every thing back -- test -- result -- same (2 come out -- suxK). Look at nozzel, it look fine to me. Last thing I have to do that disassemble that gear box...Your guys have any idea on this. I think it VER 2 from CA. thank for your help.

its gotta be the timing. ;)

Did you just install a new barrel or something, or did this start to happen all of a sudden??

It just happen after I remove gear box to re-enforce selector SW.

Do not spray crap down your magazine. You're only going to gum it up.

on my CA M4 from back in the day did that cuz my Hop Bucking was mangled, on full auto the BBS would bump eachother out of the way, so the double BB shot wasnt too noticeable, but on semi it made it abundantly clear that a BB was getting caught, and when id pull the trigger 2 would pop out.

hmm whats up with the timing? has to be it!

i found out the problem that tapped plate damaged. when the cam gear rolling it push this plate twice, one long stroke and another small stroke in 1 round. I replace it AHA...test--working fine again. damm what's hell headace--spend 3 days with it. KUDO to NEO. thanks all.
