we restored a 1988 ezgo that my son adam drives. we have a problem that we are stumped on. we have changed all the batteries,pot box, controller, f and r switch, micro switches, wires. the problem is when you take off in the cart, in forward or reverse the cart seems to be full throttle than evens out. if you go to far or to fast with the gas pedal the cart falls flat,back off the cart goes again. no dead batteries or bad cables. were do we go from here? is it wired wrong? everthing is new. it seems its on or off no happy medium. please anyone who has a thought please my son is 8 and he's driving me crazy! i have to fix this thing asap! he spoiled rotten and already hinting for a new one. thanks to all bcgc
