Really hard to say without seeing the cart. I will say that it sounds like your are going thin or fat, meaning that at WOT you are lean or rich, and letting your foot off the gas allows it to return to a place where the mixture is better. I had a moped that I messed with a great deal as a kid. I fattened up the mixture, and while it originally only went 25 mph, I got it up to 35 but like you, WOT would slow it down, I had to run around 90% throttle to be fastest. Never bothered to find out what it was, but know it was fuel, just don't know if fat or thin. I suspect you likely have something similar going on.
