Ok, if we are in the "i wonder if" mode
 
yes i can see if you didn't open the unit in the proper sequence you could  
get irregularities.
 
but my failure happened after the unit had been running for several WEEKS!  
and running at the middle range of one to two bubbles per second.
 
then it went crazy and the flow was as if the needle valve was never  
partially closed.
 
Could it be that as the tank got lower the pressure varience caused the  
valve to no longer do its job correctly??????
 
This never happened withing days of a cylinder change but rather several  
weeks.
 
any engineers out there with an explanation??????
