RE: ct4s accelerating issues
pull the starter cord, watch the flywheel spin. that tells you the running direction of the motor, make the shoes fit on so the pegs holds the shoes in FRONT of your rotation. ie, you look at the flywheel and it spins counterclockewise when running, then the shoes should go to the flywheel peg, hole left, shoe hanging off to the right when on top of the flywheel.
