hello all i have 02 shuttle that i am rebuilding and was wondering if anyone knew anything about them they are a little wierd being that you ride over the front tires like a cab over bus or fire truck this is what sold me on the cart because i like to be different. But i am haveing a problem i get no traction when i take off or when i brake i just spin and slide witch is kinda fun but not for crusin with the family is this a spring issue or just need more weight over the rear tires thanks
