pneumatic problems

i have the double acting pneumatics kit. the problem is that it doesnt extend as hard as it retracts. this is exactly the opposite of what it should be based on the surface area of the piston. is there an adjustment somewhere on the switch or cylinder. it almost seems like it doesnt bleed off the air from the other side of the piston fast enough.

well, looking at the pics on vexlabs of the kit, i would guess that there is a knob right near where the hose connects into the cylinder that can be adjusted.

also, what do you think of the pnuematics? i would like to hear what someone who has them thinks of them.
