I am experiencing full auto in semi and semi in full auto this only happens for the first 3-5 shots then it works as it should. I am also experiencing a fps drop by about 70. As well as occasional double fee happens every 50-100 shots. My air compression in the gearbox is fine my air nozzel to hop up chamber is also fine.gears are all shimmed nicely sounds all good and good connections between them as well as a corrected aoe.
internals:
zci 13:1 gears ssg
full shs air compression set apart from the piston head which is asg. Cylinder port is about 2/3 away from the cylinder head.
asg ultimate 30k motor
m115 spring
gate aster running a 11.1 lipo with 25c
Prometheus barrel (6.03x128)
with a maxx cnc me pro hop up.
timed tapet plate.
fps sitting around 250
rps is around 30
anyone got any ideas
