Black sludge- No
Tight-fitting orings- Maybe to lose?
Spring binding- No
Misaligned solenoid inserts- They are installed based on ZDSPB instructions.
Weak battery- New duracel procell.
Bad regulator- Tried 5 regulators.
Bad tank regulator- Tired 3 tanks.
Since my stock bolt was working i took the sail oring off of it and put it on the lurker bolt. I notice higher peak velocity but still very bad inconsistency. Here is a video so you gust can see.
I also just tried a couple different sized sail orings and new guide orings with no changes. I then tried my hyper 2 reg on it again and I had the same inconsistencies.
