Mark,
Here in Spokane, Washington, USA...we have an abundance of Large Scaled Grass Carp in one of the major lakes near me. ( Long Lake aka: Lake Spokane )..
This is the setup that I use on a regular basis when fishing for them exclusively.
Medium/Heavy Rod, 14# Spider Wire (blue line, purple box) 1/2 oz. Egg sinker, #2 Snap Swivel, 12-16" leader (14# spider wire ) #8 or #6 Trebel Hook, baited with Night Crawler & white or orange Power Bait dough.
Carp suck in the bait, not your traditional "bite", and be patient. Once u see your rod tip react, drop tip of your rod to create slack, once the line begins to move in the water, set the hook, allow some drag because the fish will pull hard and be dead weight on your rod...good luck
