Never thought I would have a carb question but the Tri-Z I just picked up has a Mikuni flat slide TM38 carb on it. The only way to remove the throttle cable from the carb looks to be to pull the top cap which is held on by 2 screws that can't be reached with the carb in place. So do you just pull the throttle cable from the thumb throttle and pull the carb and cable as a unit? Or is there a trick I am not seeing to the carb to remove the cable?
