Please explain spring kits to me!?!

OK, just purchased a Maddmann spring kit and searched the internet machine for days with no answers to my questions.

1) Can you mix and match your hammer and valve spring? Like a soft and a hard? Or do you have to keep the pairs matched up?

2) What does a hard spring do on the valve side?

3) What does a soft spring do on the valve side?

4) What does a hard spring do on the hammer side?

5) What does a soft spring do on the hammer side?

I have a friend with a Phsycoballistics Lightning and we are trying to tune this baby up. It has a real weak velocity and are trying to repair this problem. Any ideas?

1) yes you can mix & match, actually the recommended starting setup is blue valve, green main.

2)creates more resistance to the valve opening and shuts the valve off faster
3)the opposite of 2)
4)makes the hammer smack the valve harder/ open longer
5)the opposite of 4)

make sure there are no leaks of obstructions in the body's lower tube, PB is known for poor QC; get an HPR, turn it up to 200 PSI and sweetspot from there.

On the older markers that was how you adjusted velocity was mix and match spring till we got close to velocity you wanted. (before regulator were used)
Which I think WGP was the first or Automag.

Neither - especially since Automags are regulators.

Swapping springs to control velocity was first done in Nelson and Sheridan pumps.

I believe he meant the first to use the regulator for the cocker automag comment

Aha, sorry... Then yes, I'm pretty sure that the Automag was the first marker to come with a regulator.

How would you configure the springs and your reg for the smoothest shot possible? Are kits recommended for high end cockers like Karni's or are those dialed in pretty well already..

1) lightest mainspring with hardest valve spring that will allow ~300 fps without turning the IVG more than a couple of turns in. That will lower your LPR as low as it'll go, making the cocking action softer.

2) spring kits are recommended for the serious tinkerer/pump player or very inefficient markers (forced LP, like the later SystemX 'cockers). Karni's are already pretty well dialed in, but with the proper spring kits (belasales or any kit with a yellow strength mainspring), they can only get better (IF YOU KNOW WHAT YOU'RE DOING). You can tune for smoothness & efficiency, strike a balance in between or go nuts on LP/HP operation for quiet/straight CO2 E-sniper configurations (never understood the appeal of E-snipers). Re-springing a karni can be a pain with the ICS though.

Basically, the desired effect dictates what springs you'll be using.

karni uses shorter hammer spring because of the ics they have. leave it stock you should be good to go and they want you to adjust the reg for your velocity control.
