Hello everyone, brand new to this forums, i decided to pick up a go kart (klipper) with a motor in rough shape for 30.00 and found a craftsman 5.5hp pressure washer motor today for another 30.00 and now im having trouble trying to figure out what the deal is with the pressure washer shaft, seems to have a bearing of some soft stuck on the shaft.. does this shaft slide off with some sort of trick or what? i feel like im going to break it with the force ive been using but it still wont budge.. any advice would be greatful! i added pictures of the pressure washer with that bearing piece connected to the shaft as well as the clutch and shaft from the motor that came with the kart so you know what im working with. thanks!
also, how do i connect the gas peddle cable to this throttle? i found the throttle lever on the motor but it barely moves when i use the slider on the outside...
