As Lefty said around 10 lbs... But we have test a few sets at 8lbs up to 13lbs and of course both springs are not equal tension, Usually 1 to 2 lbs off.
it'd be a good idea to get a billet rod too since you removed (bypassed?) the gov. if you only bypassed it, you have to remove it anyways to install the rod.

I see that you've done some nice work on your engine. Can you recommend what to drill the jet out to? I know there's a process to go through involving running the kart, pulling the plug, and checking it to determine if jet size is right but is there a basic size that will work well?
drill the main out with a #65 (.035") drill this will give you a #90 jet. I also drill my slow/idle jet with a #77 drill. This reduces the deceleration popping and easier cold starts
