On the 1980 Yamaha GT80 in which position should the lever be to turn the choke on? Mine will only run in the down position which lifts the little plunger inside the carb. When i lift the lever up, it dies out. It starts cold with the lever down, which I assume would be choking it. But it runs perfect with in that position. So that is why I am not sure of which position the lever should be in to have the choke off.
