LX set up

It's all a function of the velocity. You need to have at least 20 fps between when it just starts shooting and your desired velocity. That should give you a nice soft setup that is reliable and doesn't chuff.

Well then how come I was shooting only above 280fps with the smallest spring, I have yet to re chrono but we will see.

The reason why you could not get the gun to cycle under 300 was because the carrier oring was too tight.

the way that the level 10 works is that if there is force applied to the bolt then it will vent the air (chuff) instead of cycle the bolt. the amount of force needed to be applied to the bolt before it chuffs is based on many variables. the springs force in the bolt, the carrier oring's "sticktion" and pressure to the system (fps adjustment).
If the spring is too big & much force is applied to the bolt it won't cycle, if the carrier is not lubed or is too tight it will also cause the bolt to not cycle. However just about any set up can be MADE to cycle by cranking up the velocity, with a high velocity the gun will fire regardless and won't vent...I wouldn't try the finger in the breech test on a set up like that.

SO you are saying I should not have the velocity problem anymore. Well I will report back tommarow.
