just replaced the cables on my 1985 115 evinrude. the throttle arm seems to be sticking. when i go to wot then back to natural the throttle arm doesn't go back to idle. the motor stays reved up about 1/4 throttle. same thing from natural to reverse and back.i can push the arm back to ide like theres slack in the cables. <br /><br />this was the reason i replaced the cables to begin with. thought the cables had to much slack. what could be the problem with this throttle arm? thanks for any help.
