Nice Imp!!!  Great price and find.

what ndz part did it come with out of curiosity?

for the dwell, put you reg pressure at about 180 (unless that's different for an adrenaline).  then fire a few shots near a chrono.  lower or raise the dwell when you are between 290-300 but not over 300.  that should lock it all in

12 seems a little high, but you can start there and go down, or start at 4 and go up.  what is the reg set at currently?

that may be why the dwell is so high.  less pressure = more dwell needed.  more pressure = less dwell.  tis one of the reasons why people like additional low pressure regs.  they can lower the pressure to the noid, and raise the pressure to the valve/breech.  this can't be done normally as the noid can go pop around 200.

but yeah,  at the chrono see what it's firing at while still at 160.  if it's in the right range raise the pressure and lower the dwell, you'll get more shots out of your tank too.  if it's high just lower the dwell.

lol you're welcome, they aren't that complicated when you picture what the air is doing.  have you checked out the I-O Library here?  i spent like 3 days reading that section.  it's great.

very nice gun! I was tempted to scoop this up myself. You don't see as many dust black AI's as you might think. Gloss black are everywhere..but not dust.

it's tough to say exactly what to set your dwell at. it depends on the internals. sometimes its easier to set your dwell to 0...and then go up from there until you reach the correct FPS.

not too mention...that stick trigger is rare in its own right. Don't let that puppy go. She's definitely a keeper!

Do you still have "the oldie?"  Don't forget to pop the pictures into your profile.  After you get a better shot of the new one though.  Try shooting against a dull background so I can see that trigger that Lights is raving about.
