Model 98 low pressure noise issue

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

Model 98 circa 2000, stock everything except for a TMA double trigger and a rocket cock. With fresh tank, all I can get out of it is the familiar "low air" "farting" sound. As if there is barely enough pressure to push the bolt back and forth and not enough to go through a full cycle. I even tried with my compressed air tank, I got the same results.
The springs and o-rings are brand new from the rebuild kit. Still, I can't get it to behave. 
Help?

[Edit]
Backwards Ball Detent was likely the culprit. Slowed down the bolt enough not to reset. 
Carry on.
